Post-World War II prosperity was an era of significant economic growth and rising living standards in the United States, driven by a transition from wartime to civilian production, increased consumer spending fueled by savings and the GI Bill, strong industrial growth, the expansion of the suburbs, and large-scale public infrastructure projects like the Interstate Highway System. This period saw the US emerge as a global economic powerhouse, experiencing increased homeownership, consumerism, and a widespread optimistic outlook on the future. 

Key Factors of Post-War Prosperity

• Industrial Conversion: Factories rapidly shifted from producing military goods to consumer products like cars, appliances, and televisions, meeting pent-up demand. 
• Consumerism: High consumer demand for new goods was supported by wartime savings and increased disposable income, leading to a boom in the production and purchase of goods. 
• The GI Bill: The Servicemen’s Readjustment Act of 1944 provided returning veterans with funds for higher education, home loans, and small business startups, boosting the workforce and economy. 
• Economic Strength: The US had intact infrastructure and industries while other nations struggled to rebuild, making it the sole global economic power and a sole economic powerhouse. 
• Public Spending & Infrastructure: Investments in the Interstate Highway System facilitated economic growth, and continued spending on the military-industrial complex also stimulated the economy, especially with the onset of the Cold War. 
• Suburbanization: An increase in single-family homes on the outskirts of cities led to new suburbs, shopping centers, and a rise in car ownership, with 8 out of 10 Americans owning a car by the end of the decade. 

Impact on American Life

• Rising Living Standards: For many Americans, living standards increased significantly, with more purchasing power and access to new goods and services. 
• Cultural Transformation: The era fostered a confident and optimistic American culture, marked by the Baby Boom and a new focus on family and home life. 
• Economic Dominance: The US became the world’s richest and most powerful nation, with its GDP growing substantially and its industrial output dominating the global market. 

In the summer of 1945, as World War II drew to a close, the U.S. economy was poised on the edge of an uncertain future. Would it be able to transition from a full-bore war economy to a fulsome and stable peacetime one? Many experts at the time had serious doubts.

As it turned out, after a half-decade of rationing and war privation, Americans were more than ready to splurge. And postwar U.S. industries pivoted more nimbly than expected, shifting from producing bomber jets and tanks to cars, TVs and home appliances. Here’s how America made the shift.

The period from the end of World War II to the early 1970s was a golden era of economic growth. $200 billion in war bonds matured, and the G.I. Bill financed a well-educated workforce. The middle class swelled, as did GDP and productivity. This growth was distributed fairly evenly across the economic classes though not race,^[215] which some attribute to the strength of labor unions in this period—labor union membership peaked historically in the U.S. during the 1950s, in the midst of this massive economic growth. Much of the growth came from the movement of low income farm workers into better paying jobs in the towns and cities—a process largely completed by 1960.

Congress created the Council of Economic Advisors, to promote high employment, high profits and low inflation. The Eisenhower administration (1953–1961) supported an activist contracyclical approach that helped to establish Keynesianism as a bipartisan economic policy for the nation. Especially important in formulating the CEA response to the recession—accelerating public works programs, easing credit, and reducing taxes—were Arthur F. Burns and Neil H. Jacoby. “I am now a Keynesian in economics”, proclaimed Republican President Richard Nixon in 1969. Although this period brought economic expansion to the country as a whole, it was not recession proof. The recessions of 1945, 1949, 1953, 1958, and 1960 saw a drastic decline in GDP.

The “Baby Boom” saw a dramatic increase in fertility in the period 1942–1957; it was caused by delayed marriages and childbearing during depression years, a surge in prosperity, a demand for suburban single-family homes (as opposed to inner city apartments) and new optimism about the future. The boom crested about 1957, then slowly declined.

Agriculture

Farm machinery, fertilizer and high yield seed varieties

Ammonia from plants built during World War II to make explosives became available for making fertilizers, leading to a permanent decline in real fertilizer prices. The early 1950s was the peak period for tractor sales in the U.S. as the few remaining horses and mules were phased out. The horsepower of farm machinery underwent a large expansion. A successful cotton picking machine was introduced in 1949. The machine could do the work of 50 men picking by hand.

Research on plant breeding produced varieties of grain crops that could produce high yields with heavy fertilizer input. This resulted in the Green revolution, beginning in the 1940s. By the century’s end yields of corn (maize) rose by a factor of over four. Wheat and soybean yields also rose significantly.

Government policies

The New Deal era farm programs were continued into the 1940s and 1950s, with the goal of supporting the prices received by farmers. Typical programs involved farm loans, commodity subsidies, and price supports. The rapid decline in the farm population led to a smaller voice in Congress. So the well-organized Farm Bureau and other lobbyists, worked in the 1970s to appeal to urban Congressman through food stamp programs for the poor. By 2000, the food stamp program was the largest component of the farm bill. In 2010, the Tea Party movement brought in many Republicans committed to cutting all federal subsidies, including those in agriculture. Meanwhile, urban Democrats strongly opposed reductions, pointing to the severe hardships caused by the 2008–10 economic recession. The Agricultural Act of 2014 saw many rural Republican Congressman voting against the program despite its support from farmers; it passed with urban support.

War Mobilization Had Overtaken the Homefront

Since President Franklin D. Roosevelt’s call in late 1940 for the United States to serve as the “arsenal of democracy,” American industry had stepped up to meet the challenge. U.S. factories built to mass-produce automobiles had retooled to churn out airplanes, engines, guns and other supplies at unprecedented rates. At the peak of its war effort, in late 1943 and early 1944, the United States was manufacturing almost as many munitions as all of its allies and enemies combined.

On the home front, the massive mobilization effort during World War II had put Americans back to work. Unemployment, which had reached 25 percent during the Great Depression and hovered at 14.6 percent in 1939, had dropped to 1.2 percent by 1944—still a record low in the nation’s history.

Even before the war ended, U.S. business, military and government officials began debating the question of the country’s reconversion from military to civilian production. In 1944, Donald Nelson of the War Production Board (WFB) proposed a plan that would reconvert idle factories to civilian production. Powerful military and business leaders pushed back, and plans for widespread reconversion were postponed.

But with the war wrapping up, and millions of men and women in uniform scheduled to return home, the nation’s military-focused economy wasn’t necessarily prepared to welcome them back. As Arthur Herman wrote in his book Freedom’s Forge: How American Business Produced Victory in World War II, U.S. businesses at the time were still “geared around producing tanks and planes, not clapboard houses and refrigerators.”

Some economists even predicted a new crisis of mass unemployment and inflation, arguing that private businesses couldn’t possibly generate the massive amounts of capital necessary to run the pumped-up wartime factories during peacetime. A report released in mid-1945 by Senator James Mead of New York took this opinion, arguing that if the war in the Pacific ended quickly, “the United States would find itself largely unprepared to overcome unemployment on a large scale.”

Aircraft and air transportation industries

Air transport was a major beneficiary of the war. The United States was the leading producer of combat aircraft during World War II and had a large surplus of machine tools and manufacturing facilities for airplanes at the end of the war. There were also experienced airplane manufacturing and maintenance personnel. Additionally, radar had been developed just before the war.

The aircraft industry had the highest productivity growth of any major industry, growing by 8.9% per year in 1929–1966.

During World War II the United States hired hundreds of thousands of workers, put them all in 4 major factories and had a government budget of over $3 billion (equivalent to $44,325,000,000 in 2019). The B-29 project required the US Army Air Forces to have unprecedented organizational capabilities as this project included several major private contractors and labor unions. American aircraft production was the single largest sector of the war economy, costing $45 billion (almost a quarter of the $183 billion spent on war production), employing a staggering two million workers, and, most importantly, producing over 125,000 aircraft. Production of Selected U.S. Military Aircraft (1941–1945): Bombers-49,123 Fighters-63,933 Cargo-14,710 Total-127,766.

After All That War Rationing, Americans Were Ready to Spend

Most returning veterans had no trouble finding jobs, according to Herman. U.S. factories that had proven so essential to the war effort quickly mobilized for peacetime, rising to meet the needs of consumers who had been encouraged to save up their money in preparation for just such a post-war boom.

By the summer of 1945, Americans had been living under wartime rationing policies for more than three years, including limits on such common goods as rubber, sugar, gasoline, fuel oil, coffee, meat, butter, milk and soap. Meanwhile, the U.S. government’s Office of Price Administration (OPA) had encouraged the public to save up their money (ideally by buying war bonds) for a brighter future. In her book A Consumer’s Republic: The Politics of Mass Consumption in Postwar America, Lizabeth Cohen reported that by 1945, Americans were saving an average of 21 percent of their personal disposable income, compared to just 3 percent in the 1920s.

With the war finally over, American consumers were eager to spend their money on everything from big-ticket items like homes, cars, and furniture to appliances, clothing, shoes, and everything else in between. U.S. factories answered their call, beginning with the automobile industry. New car sales quadrupled between 1945 and 1955, and by the end of the 1950s, some 75 percent of American households owned at least one car. In 1965, the nation’s automobile industry reached its peak, producing 11.1 million new cars, trucks, and buses and accounting for one out of every six American jobs.

Housing

Very little housing had been built during the Great Depression and World War II, except for emergency quarters near war industries. Overcrowded and inadequate apartments was the common condition. Some suburbs had developed around large cities where there was rail transportation to the jobs downtown. However, the real growth in suburbia depended on the availability of automobiles, highways, and inexpensive housing. The population had grown, and the stock of family savings had accumulated the money for down payments, automobiles and appliances. The product was a great housing boom. Whereas an average of 316,000 new housing non-farm units had been constructed from the 1930s through 1945, there were 1,450,000 units built annually from 1946 through 1955.

The G.I. Bill of Rights guaranteed low cost loans for veterans, with very low down payments, and low interest rates. With 16 million eligible veterans, the opportunity to buy a house was suddenly at hand. In 1947 alone, 540,000 veterans bought one; their average price was $7300. The construction industry kept prices low by standardization – for example standardizing sizes for kitchen cabinets, refrigerators and stoves, allowed for mass production of kitchen furnishings. Developers purchased empty land just outside the city, installed tract houses based on a handful of designs, and provided streets and utilities, or local public officials race to build schools. The most famous development was Levittown, in Long Island just east of New York City. It offered a new house for $1000 down, and $70 a month; it featured three bedrooms, fireplace, gas range and gas furnace, and a landscaped lot of 75 by 100 feet, all for a total price of $10,000. Veterans could get one with a much lower down payment.

Residential construction companies also mobilized to capitalize on a similar surge in housing demand, as Federal Housing Administration (FHA) loans and the GI Bill gave many (but not all) returning veterans the ability to buy a home. Companies like Levitt & Son, based in New York, found success applying the mass-production techniques of the auto industry to home building. Between 1946 and the early 1960s, Levitt & Son built three residential communities (including more than 17,000 homes), finishing as many as 30 houses a day.

New home buyers needed appliances to fill those homes, and companies like Frigidaire (a division of General Motors) responded to that need. During the war, Frigidaire’s assembly lines had transitioned to building machine guns and B-29 propeller assemblies. After the war, the brand expanded its home appliance business, introducing revolutionary products like clothes washers and dryers, dishwashers and garbage disposals.

Driven by growing consumer demand, as well as the continuing expansion of the military-industrial complex as the Cold War ramped up, the United States reached new heights of prosperity in the years after World War II. Gross national product (GNP), which measured all goods and services produced, skyrocketed to $300 billion by 1950, compared to just $200 billion in 1940. By 1960, it had topped $500 billion, firmly establishing the United States as the richest and most powerful nation in the world.

Interstate highway system

Construction of the Interstate Highway System began in 1956 under President Eisenhower. In long-term perspective the interstate highway system was a remarkable success, that has done much to sustain Eisenhower’s positive reputation. Although there have been objections to the negative impact of clearing neighborhoods in cities, the system has been well received. The railroad system for passengers and freight declined sharply, but the trucking expanded dramatically and the cost of shipping and travel fell sharply. Suburbanization became widespread, with the rapid growth of easily accessible, larger, cheaper housing than was available in the overcrowded central cities. Tourism dramatically expanded as well, creating a demand for more service stations, motels, restaurants and visitor attractions. There was much more long-distance movement to the Sunbelt for winter vacations, or for permanent relocation, with convenient access to visits to relatives back home. In rural areas, towns and small cities off the grid lost out as shoppers followed the interstate, and new factories were located near them.

Computer technology

Mainframe business computer systems were introduced in the 1950s following the manufacture of transistors. Mainframe computers were in widespread use by the 1960s. These computers handled a variety of accounting, billing and payroll applications.

One highly significant application was the Sabre airline reservations system, which first went into operation in 1960. With Sabre reservations could be placed remotely using teleprinters and all functions were done automatically, including ticket printing. This eliminated manually handling file cards.

Fiscal policy

Federal taxes on incomes, profits and payrolls had risen to high levels during World War II and had been cut back only slowly; the highest rates for individuals reached the 90% level. Congress cut tax rates in 1964. President Lyndon B. Johnson (1963–69) dreamed of creating a “Great Society“, and began many new social programs to that end, such as Medicaid and Medicare. During the Korean War, the Economic Stabilization Agency supervised price controls.

Military and space spending

After the Cold War began in 1947, and especially after the Korean War began in 1950, the government adopted a strategy in NSC 68 military spending. Economists examined how much this “military Keynesianism” stimulated the economy.

President Eisenhower feared that excessive military spending would damage the economy, so he downsized the Army after Korea and shifted priorities to missiles and nuclear weapons (which were much less expensive than army divisions). He also promoted the Interstate Highway system as necessary for national defense, and made space exploration a priority. His successor John F. Kennedy made a crewed mission to the moon a national priority. Much of the new spending went to California and the West, a continuation of wartime spending.

An even greater impact came in the South, where it stimulated a modernization of the economy away from cotton towards manufacturing and high technology. For example, there were new, large technologically sophisticated installations at the Atomic Energy Commission’s Savannah River Site in South Carolina; the Redstone Arsenal at Huntsville, Alabama; nuclear research facilities at Oak Ridge, Tennessee; and space facilities at Cape Canaveral, Florida, at the Lyndon B. Johnson Space Center in Houston, and at the John C. Stennis Space Center in Mississippi.

The Defense Department financed some of private industry’s research and development throughout these decades, most notably ARPANET (which would become the Internet).

Decline of labor unions

The percentage of workers belonging to a union (or “density”) in the United States peaked in 1954 at almost 35% and the total number of union members peaked in 1979 at an estimated 21.0 million. Union membership has continued to decline into the 2010s due to right-to-work laws adopted by many states, globalization undermining higher-wage firms, and increasing political opposition exemplified by the breaking of the 1981 strike of the Professional Air Traffic Controllers Organization (1968) by President Ronald Reagan.

The Real Reason the American Economy Boomed After World War II

The United States long reserved its most lucrative occupations for an elite class of white men. Those men held power by selling everyone else a myth: The biggest threat to workers like you are workers who do not look like you. Again and again, they told working-class white men that they were losing out on good jobs to women, nonwhite men and immigrants.

It was, and remains, a politically potent lie. It is undercut by the real story of how America engineered its Golden Era of shared prosperity — the great middle-class expansion in the decades after World War II.

Americans deserve to know the truth about that Golden Era, which was not the whitewashed, “Leave It to Beaver” tale that so many people have been led to believe. They deserve to know who built the middle class and can actually rebuild it, for all workers, no matter their race or gender or hometown.

We need to hear it now, as our nation is immersed in a pandemic recession and a summer of protests demanding equality, and as American workers struggle to shake off decades of sluggish wage growth. We need to hear it because it is a beacon of hope in a bleak time for our economy, but more important because the lies that elite white men peddle about workers in conflict have made the economy worse for everyone, for far too long.

The hopeful truth is that when Americans band together to force open the gates of opportunity for women, for Black men, for the groups that have long been oppressed in our economy, everyone gets ahead.

I have spent my career as an economics reporter consumed by the questions of how America might revive the Golden Era of the middle class that boomed after World War II. I have searched for the secret to restoring prosperity for the sons of lumber-mill workers in my home county, where the timber industry crashed in the 1980s, or the burned-out factories along the Ohio River, where I chased politicians in the early 2000s who were promising — and failing — to bring the good jobs back.

The old jobs are not coming back. What I have learned over time is that our best hope to create a new wave of good ones is to invest in the groups of Americans who were responsible for the success of our economy at the time it worked best for working people.

The economy thrived after World War II in large part because America made it easier for people who had been previously shut out of economic opportunity — women, minority groups, immigrants — to enter the work force and climb the economic ladder, to make better use of their talents and potential. In 1960, cutting-edge research from economists at the University of Chicago and Stanford University has documented, more than half of Black men in America worked as janitors, freight handlers or something similar. Only 2 percent of women and Black men worked in what economists call “high-skill” jobs that pay high wages, like engineering or law. Ninety-four percent of doctors in the United States were white men.

That disparity was by design. It protected white male elites. Everyone else was barred entry to top professions by overt discrimination, inequality of schooling, social convention and, often, the law itself. They were devalued as humans and as workers. (Slavery was the greatest devaluation, but the gates of opportunity remained closed to most enslaved Americans and their descendants through Emancipation and its aftermath.)

Women and nonwhite men gradually chipped away at those barriers, in fits and starts. They seized opportunities, like a war effort creating a need for workers to replace the men being sent abroad to fight. They protested and bled and died for civil rights. And when they won victories, it wasn’t just for them, or even for people like them. They generated economic gains that helped everyone.

The Chicago and Stanford economists calculated that the simple, radical act of reducing discrimination against those groups was responsible for more than 40 percent of the country’s per-worker economic growth after 1960. It’s the reason the country could sustain rapid growth with low unemployment, yielding rising wages for everyone, including white men without college degrees.

America’s ruling elites did not learn from that success. The aggressive expansion of opportunity that had driven economic gains was choked off by a backlash to social progress in the 1970s and ’80s. The white men who ran the country declared victory over discrimination far too early, consigning the economy to slower growth. Sustained shared prosperity was replaced by widening inequality, lost jobs and decades of disappointing income growth for workers of all races.

In important ways, much of the work of breaking down discrimination stalled soon after the passage of the Civil Rights Act in 1964. “It was fundamentally over by the time of the Reagan presidency,” William A. Darity Jr., a Duke University economist who is one of his profession’s most accomplished researchers on racial discrimination, told me. Over the past several decades, some barriers to advancement for women and nonwhite men have grown back. New ones have grown up beside them.

A host of studies illustrate this. A recent and devastating one is co-authored by a University of Tennessee economic historian, Marianne Wanamaker, who served a year in the White House on President Trump’s Council of Economic Advisers. She and a co-worker went back to Reconstruction and measured how much easier it was for the sons of poor white men to climb the economic ladder than the sons of poor Black men.

In terms of economic mobility, they found, the penalty for being born Black is the same today as it was in the 1870s.

Women have made more progress in recent decades than Black men, but they are nowhere close to equality. They still earn less for the same work, and they are still blocked by harassment, discrimination and policies from reaching the same heights as white men in many of America’s most important industries.

Take Silicon Valley. In 2018, venture capitalists in the United States distributed $131 billion to start-up businesses, hoping to seed the next Google or Tesla. That money went to nearly 9,000 companies. Just over 2 percent of them were founded entirely by women. Another 12 percent had at least one female founder. The rest, 86 percent, were founded entirely by men.

The statistics show tragedy. They also show opportunity. If America can once again tear down barriers to advancement, it can tap a geyser of entrepreneurship, productivity and talent, which could by itself produce the strong growth and low unemployment that historically drive up wages for the working class, including working-class white men.

If you want to know where the new good jobs will come from — those that will help millions of Americans climb back into the middle class — this is where you should look, to the great untapped talent of America’s women, of its Black men, of the highly skilled immigrants that study after study show to be catalysts of innovation and job creation.

That is not the appeal that populist politicians make to working-class white men, who have been rocked by globalization and automation and the greed of the governing class. But it should be.

All Americans have a stake in the protests for equality they see every night on the news. Working-class white men, like the guys I went to high school with, have a bond with the Black men, the immigrants and the women of all races who have taken to the streets.

Great Responsibilities and New Global Power

World War II transformed the United States from a mid-level global power to the leader of the “free world.” With this rapid rise in power and influence, the United States had to take on new responsibilities, signaling the beginning of the “American era.”

The aftermath of World War I confirmed the importance of isolationism to many Americans. The “war to end all wars” ultimately failed to live up to its name, and Americans were wary of once again of getting involved in foreign conflicts. Before the start of World War II, the idea of the United States as a leading global power was not an ambition of American politicians. Most Americans remained content to let other powers, such as Great Britain, fill that role. By the end of World War II, however, the United States stood as one of two leading global powers, alongside the Soviet Union, which had experienced a similarly unexpected rise to power. Far from the isolationism that characterized US global politics, the immediate aftermath of World War II established a clear desire among American political and economic leaders to protect this newfound power and to secure the United States as the leader of the “free world.”

The Rising Power of the Dollar 

At end of nineteenth century, the British pound was more than double in value to its closest competitor, which included the French franc and the German mark. American dollars could not compete with European currencies. The strength of the British pound continued to persist, but its preference as a standard currency for global commerce was weakening over time. Economic scholars Menzie Chinn and Jeffrey Frankel argued that the waning power of the British pound, hit by two world wars and a global economic depression, allowed the American dollar to surpass the once robust British currency. By 1945, the status of the dollar and the pound had essentially flipped. Within a few decades, the United States transformed from an isolationist, inward-looking power with minimal presence on the global stage to an economic powerhouse that controlled the most valuable currency in international markets. How did such a remarkable transformation occur?

The decades before the start of World War I revealed signs of a strengthening US economy. The overall size of the American economy had surpassed United Kingdom as early as 1872 and continued to grow. As Chinn and Frankel pointed out, following 1914, “the US passed from net debtor to net creditor as the UK moved in the opposite direction. This had much to do with British borrowing from the United States to fight World War I.” In the successive years, US exports pulled ahead of those made in the United Kingdom. The dollar maintained stability in the 1920s, emerging as a major international currency, but due to the global depression of the 1930s, the pound retained the dominant position as the key currency of the interwar period. However, by the end of World War II, the pound could no longer compete. War, decolonization, and declining economic strength abroad dealt a lasting blow to the United Kingdom and ushered in a new era of American dominance in the arena of global influence and economic strength.

The arsenal of democracy that Franklin D. Roosevelt called into existence when the United States entered World War II proved to be a valuable investment in the American economy. By 1945, the United States was manufacturing more than half of the produced goods in the world. US exports made up more than one-third of the total global exports, and the United States held roughly two-thirds of the available gold reserves. The sudden onset of this new position of economic power presented the United States with a number of new responsibilities. The actions of American leaders would no longer only affect citizens in the United States. Such actions proved to have long-reaching repercussions across the globe.

Bretton Woods Conference

The emerging economic power of the United States came into focus even before World War II came to an end. During a conference held at Bretton Woods, New Hampshire, from July 1-22 in 1944, delegates from 44 nations met to discuss the postwar global order and establish a new international monetary system. This conference was held in an effort to avoid another global economic depression similar to the one that occurred in the interwar period. The theory that partnerships built on trade and economic ties would help discourage the outbreak of another world war led to the construction of a new International Monetary Fund (IMF) and the World Bank. Both the IMF and the World Bank were established in Washington DC, and these organizations aimed to monitor the movement, to use of funds between nations, and to provide loans to countries experiencing economic hardship. At the Bretton Woods Conference, exchange rates were linked to gold reserves, and with the United States holding the bulk of the gold reserves in the world, the dollar emerged as the new reserve currency for international commerce and trade. While the IMF would oversee the maintenance of this new global economic system, the United States and the dollar emerged as the economic standard bearers for the postwar world.

United Nations

The leading role occupied by the United States following World War II grew through the creation of the United Nations in 1945. Meeting in San Francisco, delegates from 50 countries created a charter for this new international organization, founded to prevent the outbreak of another world war. Poland later signed on, bringing the founding number of countries to 51. With the UN Charter agreed upon, the United Nations formally came into existence on October 24, 1945.

The UN built upon American President Woodrow Wilson’s idea for a League of Nations created after World War I. Based on an American idea and promoted by Roosevelt through conferences held between the Allied powers throughout World War II, the United States signed on to the UN Charter as one of its most influential members. The United States became one of five permanent members of the UN Security Council, and the United States continues to be one the largest financial contributors to the United Nations.

Marshall Plan

Emerging from World War II as a leading power, the United States took on an active role in rebuilding the war-torn cities left in the wake of this unprecedented conflict. Turning away from its previous role as an isolationist power, US leaders created the Postwar European Recovery Plan (ERP) that pumped over $13 billion into the rebuilding of Western Europe. Headed by Secretary of State George Marshall, the effort known as the “Marshall Plan” helped bolster the economic strength and international prominence of the United States in the aftermath of World War II. Standing in stark contrast to the isolationism that dominated US foreign policy following World War I, the Marshall Plan confirmed that the United States would remain engaged and active on the global stage. The United States approached the restoration of Western European economies as an investment in the preservation of peace and protection of markets for American goods. The underlying belief running through the Marshall Plan held that countries that traded together were less likely to wage war against each other.

Rebuilding the war-torn countries of Western Europe not only helped avoid another economic depression, but it also contributed to the growing competition for global dominance between the United States and the USSR. The emerging conflict between capitalist and communist countries fueled the desire of American leaders to ward off the presence of communism in Western Europe in favor of capitalist ventures. As much as the United States invested in the rebuilding of economic markets to promote its own goods and to prevent the outbreak of another global war, the Marshall Plan served as a conduit for the spread of capitalism across Western Europe, hindering the global power and influence of the Soviet Union.

Similar concerns influenced efforts to restructure the Japanese economy following a period of punishment and governmental reform overseen by General Douglas MacArthur, head of the Supreme Command of Allied Powers (SCAP) in Japan. With China on the cusp of a communist revolution, SCAP sought to rebuild Japan’s industry sector in a way that would restrict military strength and prevent the growth of communist interests. Part of the postwar economic restructuring included dissolving large-scale Japanese business conglomerates known as zaibatsu. Controlled by only a few prominent families, the zaibatsu held monopolies over much of the imperial Japanese economy, particularly in the industrial sector. In order to secure control over the rebuilding and restructuring of Japanese industry, SCAP launched an attack on the zaibatsu, forcing the dissolution of these family-run monopolies and shifting more economic power to small businesses and Japanese farmers. However, these progressive moves also increased fears that communism might take hold in Japan. While the Marshall Plan aimed to prevent the outbreak of subsequent wars while also warding off communist influence from the Soviet Union, the start of the Korean War in 1950 provided the capitalist boost for Japanese industries that American leaders sought, as Japan became the primary supplier of goods for UN forces throughout the war.

“New Markets and Industries” 

By investing in the reconstruction of countries devastated by World War II, the United States created new markets to export American goods. Products like Coca-Cola became desired commodities abroad and helped to promote the exportation of US culture. The demand for American-made goods—along with the movement of people on US commercial airlines like Pan Am or with travelers staying in American-run hotels abroad like the Hilton chain—established the United States as a global economic leader. The dominance of the American economy in the global marketplace after World War II brought significant changes to the way Americans lived their daily lives. The new prosperity led to the rise of a consumer society across the United States, with emerging middle class eagerly purchasing goods such as cars and televisions. The economic boom that followed World War II not only changed the way Americans lived each day, but it also established the United States as both a cultural leader abroad and an economic leader amongst all other nations.
