The massive dust storms caused farmers to lose their livelihoods and their homes. Deflation from the Depression aggravated the plight of Dust Bowl farmers. Prices for the crops they could grow fell below subsistence levels. In 1932, the federal government sent aid to the drought-affected states.
Roosevelt believed it was the federal government`s duty to help the American people get through the bad times like the Dust Bowl. During the first three months of his presidency, a steady stream of bills were passed to relieve poverty, reduce unemployment and speed economic recovery.
