You're gettin' there, Ashley.
When Hoover ran for President, he promised to help the Depressed Farmers who were not doing all that well--even during the prosperous 1920s.
To help aid them, Congress passed the Smoot-Hawley Tariff Act in 1930, which raised the Tarif on exported goods OBNOXIOUSLY high.
Many historians have written that this Act caused the Depression--but this is not the case--it was the Stock Market Crash in 1929 which started the Depression. Anyway, because Tariffs were so freakin' high, European exports fell to an all-time low; and this being the Depression (which hit Europe as well), the American farmers did not find the expanded markets for their goods Hoover had anticipated.
All the Tariff succeeded in doing was causing a lot of ill will between America and the European countries. Like most of Hoover's polcies, it didn't really help anybody or anything. However, a lof of these Tariffs remained on the books until after World War II was over.
Why was Spiro Agnew forced to resign as Vice-President?
