Step-by-step explanation:
The federal government directly sought to limit postwar unemployment by implementing social welfare programs and public works projects. These programs were part of the New Deal initiatives introduced by President Franklin D. Roosevelt to stimulate the economy and provide jobs for the unemployed during the Great Depression and post-World War II period. Examples of these programs include the Works Progress Administration (WPA), which employed millions of Americans in various public works projects, and the Social Security Act, which provided financial assistance to the elderly and disabled.
