Every time you buy a new phone using a monthly payment plan, you are participating in a culture of consumer credit that exploded in the United States a century ago. The 1920s economic boom did not happen by accident; it was carefully cultivated by three Republican presidents: Warren Harding, Calvin Coolidge, and Herbert Hoover. Harding campaigned on a promise of Normalcy, focusing on domestic prosperity and Isolationism after the trauma of the First World War.
The core of Republican economic policy was Laissez-faire, a belief that the government should not interfere in business. Secretary of the Treasury Andrew Mellon slashed taxes on the wealthy, culminating in the Revenue Act of 1926 which reduced the top income tax rate from 73% to just 25%. The government actively chose not to break up massive Trusts (corporate monopolies) in steel and oil, believing large corporations were more efficient. Furthermore, they did not protect workers' rights; trade union membership plummeted as courts consistently sided with business owners. This pro-business stance was later championed by Hoover as Rugged Individualism, the idea that people should be self-reliant without government welfare.
To protect American businesses from foreign competition, the government embraced Protectionism. In 1922, Harding signed the Fordney-McCumber Tariff, which raised average import duties to 38.5%, with some chemical and textile taxes reaching 400%.
This created a massive Tariff wall that made foreign goods too expensive for Americans to buy, forcing them to purchase domestic products. However, this policy backfired on American exporters. European nations responded with Retaliatory tariffs (a tariff war). For example, France raised taxes on US cars to 100%. Because European countries could not sell their goods in America, they could not earn the dollars needed to repay their wartime debts or buy American agricultural exports.
While government policies created a favorable environment, revolutionary manufacturing techniques created the actual goods. Henry Ford pioneered Mass production by introducing the moving assembly line in 1913. By Standardization of parts, Ford slashed the time needed to build a Model T from 12.5 hours to just 93 minutes.
This efficiency triggered a powerful Cycle of prosperity. Because cars were cheaper to make, the price of a Model T dropped from $850 in 1908 to roughly $290 by 1925. Ford also doubled his workers' wages to $5 a day and capped shifts at 8 hours. This meant his own employees could afford the products they were building. The motor industry acted as a catalyst for the entire economy through a "multiplier effect", consuming 20% of America's steel and 80% of its rubber by the end of the decade.
To afford these new consumer goods, Americans embraced Hire purchase, paying a small deposit upfront and clearing the balance in installments. By 1929, 60% of all cars were bought on credit.
The Mechanics of the Boom:
The "Roaring Twenties" is often remembered as an era of universal wealth, but extreme inequality was hidden beneath the surface. By 1929, 60% of American families lived below the Poverty line of $2,000 a year, while the wealthiest 5% earned a third of the nation's total income.
| Group/Industry | Status | Reasons for Outcome |
|---|---|---|
| Motor & Chemical Industries | Winners | Benefited from mass production, government protectionism (tariffs), and the multiplier effect of suburban growth. |
| Corporate Owners | Winners | Benefited directly from Laissez-faire tax cuts, the weakening of trade unions, and the freedom to form monopolies. |
| Agriculture | Losers | Suffered a severe Agricultural depression. Mechanisation (tractors) led to Overproduction. Retaliatory tariffs destroyed European export markets. Wheat prices collapsed from $2.50 to $1.00 per bushel. |
| Staple industries | Losers | Traditional industries declined. Coal lost out to hydroelectric power and oil. Northern textiles were replaced by synthetic fibres like rayon. |
| Minority Groups | Losers | African Americans in the South were trapped in Sharecropping cycles of debt, with 1 million losing farm jobs. Native Americans faced 80% unemployment on reservations. |
The government's strict adherence to Laissez-faire meant they refused to help the losers. For instance, President Coolidge twice vetoed the McNary-Haugen Bill, which would have allowed the government to buy surplus crops to raise prices, arguing it was not the state's job to manipulate free markets.
Students often confuse Laissez-faire with Protectionism. Remember that Republicans believed in non-interference at home (Laissez-faire) but heavily interfered in international trade (Protectionism/Tariffs) to help big business.
In 'Analyse' questions about the boom, do not just list causes. Examiners expect you to make explicit links—for example, explain how the Fordney-McCumber Tariff directly enabled American mass production to flourish without cheap European competition.
When evaluating the success of the boom, use the specific statistic that 60% of families lived below the $2,000 poverty line to prove that prosperity was highly unequal.

Protectionism
Economic policies, such as tariffs, designed to restrict international trade and protect domestic industries from foreign competition.
Fordney-McCumber Tariff
A 1922 law that raised average import duties to 38.5% to protect American factories from foreign competition.
Tariff wall
Extremely high taxes on imported goods that make them uncompetitive, effectively blocking them from the domestic market.

Agricultural depression
A severe economic slump in the farming sector during the 1920s characterized by falling crop prices and mass bankruptcies.
Overproduction

Staple industries
Traditional, heavy industries such as coal mining, textiles, and shipbuilding that largely struggled and declined during the 1920s.
Sharecropping
An agricultural system where tenant farmers rent land in exchange for a large share of their crops, often leading to inescapable debt.
