What was the reason for an increase in federal government spending in the 1930s?

The increase in federal government spending in the 1930s was primarily driven by the Great Depression, which created widespread economic hardship and high unemployment. In response, President Franklin D. Roosevelt implemented the New Deal, a series of programs and reforms aimed at economic recovery and social welfare. These initiatives included public works projects, financial reforms, and direct aid, significantly expanding the role of the federal government in the economy.
