In 1933 workers and businessmen marched in spectacular parades to demonstrate their support for the National Recovery Administration (NRA), Roosevelt’s agency for industrial mobilization, symbolized by its emblem, the blue eagle. Farmers were grateful for government subsidies dispensed by the newly created Agricultural Adjustment Administration
