It is unclear which specific policy the question is referring to. However, during the Great Depression, President Franklin D. Roosevelt implemented a series of economic policies known as the New Deal. His plan was to stimulate economic growth and create jobs by pumping government money back into the economy through public works projects and new government agencies, such as the Works Progress Administration and the Civilian Conservation Corps. Roosevelt also introduced various social welfare programs, such as Social Security and unemployment insurance, to provide a safety net for those who were struggling during the economic crisis. Overall, Roosevelt's goal was to create a more robust and stable economy, while also addressing social inequality and economic injustice.
