How did the people in 1930 make their money?

In the 1930s, especially during the Great Depression, many people made their money through traditional employment in industries such as agriculture, manufacturing, and services. However, due to widespread unemployment, many turned to informal work, bartering, or self-employment, including small businesses and trades. Some individuals engaged in desperate measures like scavenging or selling goods to survive. Additionally, the New Deal programs initiated by the U.S. government provided jobs and financial support to help stimulate the economy.
