- Hire purchase: "Buy now, pay later" — paying for goods in weekly instalments
- Tariff: Tax on imports to protect American manufacturers (e.g. Fordney-McCumber 1922)
- Speculation: Buying shares hoping prices will rise, not because companies earn real profit
- Overproduction: Factories producing more goods than consumers can buy — a hidden weakness of the boom

Cross-Topic Links
- → Topic 3 (America in 1920): The boom was only possible because of the starting conditions in 1920 — WW1 industrial capacity ($10 billion European debt) and Republican laissez-faire policies were already in place before the boom accelerated.
- → Topic 6 (Wealth Inequality): The boom's hidden weakness — 60% below the poverty line, credit-fuelled debt, overproduction — is the direct bridge to why the Depression hit so hard; inequality limited who actually benefited from prosperity.
- → Topic 10 (Causes of Depression): Every cause of the boom contains the seed of its collapse: credit became debt, overproduction outpaced demand, speculation on shares was unsustainable — making this topic essential for explaining why the Crash happened.
- → Topic 5 (Life Changes): The consumer goods produced by mass production (cars, radios, refrigerators) physically transformed how Americans lived, travelled, and entertained themselves, making these two topics directly complementary.
- → Topic 9 (Intolerance): The prosperity of the boom benefited white, urban, Protestant Americans most — this inequality is what fuelled WASP resentment of immigrants and minorities who were seen as threatening their privileged position.
