The u. s. stock market crash of 1929 hit america hard because

That was a giant part of our economy and people who invested in the stock market lost everything 

Because during the 1920s, the U.S stick market had fast growth, reaching its peak in 1929. By then, production had already declined unemployment had risen, leaving stick in great excess of their real value. A long with the other causes of the eventual market collapse were low wages, a struggling agricultural sector etc. HOPE THIS HELPS.❤
