The Great Depression

Why this matters

A tariff written to protect American jobs ended up costing many instead, once other countries answered Smoot-Hawley with tariffs of their own and world trade seized up. Unemployment at the crisis's worst sat alongside comparably brutal rates in Germany and Britain, proof a stock market crash in New York had become a problem no single country could fix alone.

The Dust Bowl gets treated as a separate disaster in most classrooms, but I teach it as a second collapse landing on top of the first, since farmers who had already lost savings to failed banks watched the land itself blow away. Layering the two keeps students from reaching for a single cause.

From one teacher to another

Half my students picture the Depression as one bad day on Wall Street, and the 230-point close on October 29, 1929 is where that idea comes from. I make them sit with the real number instead: the Dow bottomed out at 41 in July 1932, not October 1929, and nobody in the room between those two dates knew the bottom was still years away. They trace the loop themselves - margin calls forcing sales, sales forcing prices lower, lower prices forcing more margin calls - until a stock market problem becomes 9,000 failed banks and one in four American workers out of a job. By the time they reach FDR's inaugural address, "the only thing we have to fear is fear itself" reads less like a slogan and more like a diagnosis.
