During World War II, American servicemen, known as 'GI's', faced shortages and homesickness, with over 292,000 casualties. Women entered the workforce in large numbers, earning 60% of men's pay, and many served in military roles despite losing their jobs when the war ended. The American public participated in rationing efforts, contributed significantly to the war through various means, and increased participation from African Americans, Latinos, Native Americans, and Jewish Americans was observed, despite ongoing prejudices.
