Discuss THREE ways that WWWII showed the problems of inequality, racism and sexism that was present in our society at that time.

Women were welcomed and encouraged by the government and
society to work long hours in the war factories, as long as they gave up those jobs when
the men returned.  They were kept from combat duty, almost always employed in an
auxiliary role, and rarely given promotions to higher
ranks.

African-Americans served in segregated units, meant
mostly to serve as supply units and graves details (with notable exceptions - see
Tuskegee Airmen and armored divisions), and again, were rarely given command ranks. 
African-American civilians in war factories were paid less than whites until FDR signed
an executive order ending the practice.  In civilian life, they were still paid less
tough, and segregated by Jim Crow laws.
