Topic 8.4 Notes – Economy After 1945
What Drove Postwar Economic Growth
The United States came out of World War II in a rare position. Its factories, cities, and transportation systems were still standing, unlike much of Europe and Asia. Wartime production had already ended Depression unemployment and expanded industry, science, and technology.
Four causes worked together, not separately:
- Private sector expansion converted wartime factories into producers of cars, televisions, refrigerators, and washing machines.
- Federal policy and spending kept demand strong through benefits, housing support, defense contracts, and research.
- Baby boom families needed houses, schools, appliances, and later college and jobs.
- Technological development raised productivity and opened new regions to growth.
This produced rising wages, consumer spending, homeownership, and a larger middle class. The key qualification is that prosperity was broad, not universal.
The Four Main Causes of Growth
Expanding private sector
Businesses shifted from tanks and planes to consumer durables. Mass production lowered prices, advertising pushed demand, and installment buying plus consumer credit let families buy expensive goods over time.
Big purchases created a chain reaction. A car boosted steel, rubber, petroleum, glass, insurance, and road construction. A house boosted lumber, furniture, appliances, construction, and retail. Large corporations grew, and so did service and white-collar work.
Federal spending and policy
The postwar economy was a mixed economy. Private business led production, but government supported stability and demand. Truman’s Fair Deal and Eisenhower’s Modern Republicanism both accepted that the federal government should help maintain prosperity.
Examples students forget to connect:
- Social Security expansion
- minimum wage increases
- housing assistance
- defense contracts
- scientific research
G.I. Bill
The clearest example was the Servicemen’s Readjustment Act of 1944, usually called the G.I. Bill.
- Paid for college and vocational training
- Guaranteed home, farm, and business loans
- Provided unemployment pay for veterans
That meant more college students, more skilled workers, more homeowners, and more construction.
Baby boom
From 1946 to 1964, about 76 million babies were born. Returning veterans, early marriage, economic confidence, and suburban housing all fed this boom. The fertility rate rose sharply after World War II and stayed elevated through the late 1950s, which is the pattern shown here.

The boom increased demand first for homes and baby products, then for schools, colleges, and jobs.
Technological development
Cold War research pushed aviation, electronics, nuclear technology, synthetic materials, and early computers. Federal military contracts linked universities, government, and private industry.
Two effects matter a lot:
- Air conditioning helped the South and West grow.
- Agricultural mechanization reduced farm jobs and pushed people toward metropolitan areas.
How Growth Changed Where Americans Lived
Suburbanization
Middle-class families moved from cities and rural areas to suburbs because of housing shortages, the baby boom, rising incomes, FHA and VA mortgages, cars, highways, and mass-produced homes.
Levittown is the standard example. William Levitt used assembly-line building methods to make affordable suburban homes.
Suburbs increased demand for cars, shopping centers, appliances, and local services. They also drained tax money and people from many cities through white flight and decentralization.
The Interstate Highway System
The Federal-Aid Highway Act of 1956 created a huge highway network. It supported commuting, trucking, tourism, suburban growth, and national markets. It also cut through and damaged some urban neighborhoods.
Migration to the Sun Belt
The South and West grew fast after 1945. California, Texas, Florida, and Arizona became major examples.
Pull factors included:
- defense spending and military bases
- aerospace, oil, electronics, construction, tourism
- lower taxes and weaker unions
- cheap land
- warm climate
- air conditioning
This drew veterans, young families, retirees, skilled workers, and many African Americans in the Second Great Migration. Population growth gave the Sun Belt more House seats and Electoral College votes.
Who Benefited and Who Was Left Out
Postwar affluence reached many Americans, but not all. Unions like the UAW and steel unions won higher wages, pensions, and health insurance for many workers. The Taft-Hartley Act of 1947 limited union power and encouraged right-to-work laws.
Racial inequality was built into prosperity:
- Black veterans were often blocked from full G.I. Bill access by segregated colleges, local control, and discriminatory banks.
- FHA/VA lending, redlining, restrictive covenants, and developer exclusion limited minority homeownership.
- Shelley v. Kraemer (1948) stopped court enforcement of restrictive covenants, but discrimination continued.
- Levittown originally excluded Black buyers.
Women were pushed toward domestic ideals, but many kept working, often in lower-paid jobs.
The Cause-and-Effect Chain to Lock In
Postwar growth came from interaction:
- G.I. Bill led to college and mortgages.
- College led to skilled jobs, mortgages led to homeownership.
- Homebuilding led to construction and consumer spending.
- Highways + cars + suburbs led to commuting, shopping centers, and decentralization.
- Defense spending + air conditioning + jobs led to Sun Belt growth.
Key Takeaways
Postwar Economic Boom
Late-1940s–1960s expansion driven by a growing private sector, federal spending, pent-up demand, the baby boom, and new technology
Pent-Up Demand
Postwar surge in consumer spending after wartime rationing and shortages delayed purchases while workers accumulated savings
Mixed Economy
Economy in which private firms direct most production while government supports demand through benefits, infrastructure, research, regulation, and contracts
Harry Truman
President whose Fair Deal sought to extend New Deal liberalism through expanded benefits, housing aid, health insurance, and civil rights measures
Fair Deal
Truman program proposing expanded Social Security, a higher minimum wage, housing aid, national health insurance, and civil rights; Congress enacted only parts
Dwight D. Eisenhower
President who practiced Modern Republicanism, preserved major New Deal programs, and supported defense, research, and interstate highway spending
Modern Republicanism
Eisenhower's moderate policy of fiscal restraint and private enterprise combined with acceptance of New Deal programs and major federal investments
John F. Kennedy
President whose New Frontier proposed federal action in education, cities, science, welfare, and economic growth

Mass-Consumption Economy
Postwar economy sustained by rising wages, savings, credit, advertising, and widespread purchases of homes, automobiles, appliances, and other consumer goods
Taft–Hartley Act of 1947

Right-to-Work Laws
State laws permitted by Taft–Hartley that prohibit requiring workers to join or financially support a union as a condition of employment

Air Conditioning
Technology that made homes and workplaces practical in hot climates, removing an obstacle to population and business growth in the Sun Belt
Agricultural Mechanization
