Identity/Membership
The war put much emphasis on the divide between We versus Them. War propaganda fired up both women and men to fight for their country. It was the Allies against the Germans and Italians, and the U.S.A. was very supportive of their own country during the war. It encouraged the people to continue serving their country and putting their country’s needs before their own. Therefore, women would work hard at their jobs while the men would fight for their lives.
Identity cards were given to people so that the government would know that they weren't the enemy. They were also shown when receiving rations so that the people could not cheat and get more than they're allowed.
