Answer:
Many many Americans lost their jobs. They had no stable work, which meant no money for food, rent, or heath. The Americans that lost their homes were eventually placed in Hoovervilles; poor tenement style setups that were temporary homes. Many veterans didn't get their pension, which caused many riots. The families that lived in Oklahoma were in the middle of the Dust Bowl because that land was stripped of nutrients and was sand-like. Many families moved to California for work, only to find none.
