The Fordney-McCumber Tariff of 1922 wasn’t appreciably different from the Smoot-Hawley Tariff of 1930. The US basically had an unchanged level of taxation beginning with 1922.
The primary cause of the Great Depression was a collapse in the US banking system, as described by Friedman & Schwartz and Joseph Schumpeter.
Smoot-Hawley is what contemporaneous writers latched onto as a cause but the real damage was 30% of the American money supply evaporating in a series of cascading bank failures from 1930-33.
My g-grandfather just put his two weeks pay in the bank in a little town in Iowa.
The next day, the bank closed.
The same family is running a bank nearby.
