Hoover was a big government man. When the Wall Street Crash of 1929 struck less than eight months after he took office, Hoover tried to combat the ensuing Great Depression with volunteer efforts, public works projects such as the Hoover Dam, tariffs such as the Smoot-Hawley Tariff, an increase in the top tax bracket from 25% to 63% and increases in corporate taxes. Smoot-Hawley tariff was largely responsible for starting a trade war that drove the whole world into the Great Depression and probably WWII. Hoover's tax increases turned a recession into a Depression. FDR's policies kept the Depression going until rescued by WWII which forced our way out of it. His wartime policies caused serious economic problems after he died.
