Why did the government help support the arts in the 1930s

Art during the 1930's was dominated by the great depression. It was used as a form of entertainment during the harsh time. Also, art was influenced by social, political, and world events going on in that time period. The artists painted their experiences from the World War, the great depression, and the rise of Nazism.
