Herbert Hoover believed the best action during the Great Depression was for the government to have minimal involvement and for local charities to help the needy. However, his efforts to find solutions were unsuccessful. The Dust Bowl in the 1930s caused major agricultural damage in the Great Plains through dust storms, which were worsened by drought and poor farming practices. This led thousands of families to migrate west in search of work, establishing makeshift towns called "Hoovervilles".
