World War 2 had widespread impacts across the United States and Germany in terms of economic planning, social changes, and technological/industrial development. In the US, women entered the workforce in factories and shipbuilding. The government instituted wage and price controls and regulated unions. Japanese Americans were discriminated against and forced into internment camps. Germany remilitarized beginning in 1935 in violation of Treaty of Versailles and developed its air force and submarine fleets while instituting discriminatory policies that put many groups in concentration camps.
