When the Wall Street Crash of 1929 struck less than eight months after he took office, Hoover tried to combat the ensuing Great Depression in the United States with large-scale government public works projects such as the Hoover Dam, and calls on industry to keep wages high.
 Liberals claim that Hoover's laissez-faire caused the Great  Depression, but the opposite is true. His interventions caused it.    While not believing in charity by the government, Hoover did try  and help the economic mess that began during his administration.He  gave much of his money to charity and encouraged Americans to do  the same.  Hoover tried to help by pressuring business leaders to keep wages  high when economic conditions dictated that they fall. Professor  Lee E. Ohanian calculates that this accounts for as much as 2/3 of  the unemployment in the first years of the Great Depression.
