Hanke says that the most repeated statement about the cause of the U.S. Great Depression is that it was caused by the October 1929 stock market crash. How could that be? By April 1930, the stock market had recovered to its pre-crash level. What is not taught in history books is the Great Depression was caused by a massive government failure. The most important part of that failure were the actions by the Federal Reserve Bank that led to the contraction of the money supply by 25 percent. Then, the name of saving jobs, Congress enacted the Smoot-Hawley Act in June 1930, which increased U.S. tariffs by more than 50 percent. Other nations retaliated and world trade collapsed. U.S. unemployment rose from 8 percent in 1930 to 25 percent in 1933. In 1932, the Herbert Hoover administration and a Democratic Congress imposed the largest tax increase in U.S. history, raising the top tax rate on income from 25 percent to 63 percent. The Roosevelt administration followed these destructive policies with New Deal legislation that massively regulated the economy and extended the Great Depression to after World War II.
How about a bit of history? Between 1787 and 1930, our nation has seen both mild and severe economic downturns, sometimes called Panics, that have ranged from one to seven years. During that interval, there was no thought that Congress or the president should intervene in the economy to enact stimulus packages, jobs programs or massive corporate handouts. Probably, the reason that no one thought to do so was that there was no constitutional authority to do so. It took the Herbert Hoover and Franklin Roosevelt administrations to massively and unconstitutionally intervene in the economy and, with the help of a frightened, derelict U.S. Supreme Court, turn what might have been a two- or three-year sharp downturn into our longest depression.
