Question

What progress did veterans make in the post war period

Answer 1

In the 40 years after WWII (1945-1985) the 'Postwar Period'.... 
WWII and Korean War veterans got the 'GI Bill' which allowed them to buy land and houses with free mortgages (no interest/ down payment) and free veteran medical care in return for their war service. This allowed the ex soldiers who were mostly poor to buy houses/ land they otherwise could not and move into the American 'middle class' making the 'American Dream' for them come true. 
Women had the 'Women's Liberation Movement' and Equal Rights Movement (1965-1985) poured women into the US workforce, making the US workforce 1/2 female 1/2 male, freed them from marriages they didn't like, and gave them equal or preferential pay/ rights. 
African Americans in the 'Civil Rights Movement' 1957-1980's got the end of 'segregation' and mistreatment by the US South, the end of mistreatment generally, end of discrimination, fair voting in the South, equal rights, and by year 2000 mostly the end of 'racism'.
