The fair deal was a legislation program announced by President Truman in 1945.President Truman called the Congress to increase the minimum wage, expand the public housing, Social Security, national health insurance, and aid to education. The purpose of this legislation aimed the economy from wartime to peacetime.

I think this such of legislation program was a  inevitable result after WWII because the goverment had to do something to help those soldiers. In order to  give them a stable life, the goverment provided them a job, house and education opprturnity.
