What was designed to economically help soldiers coming home from World War II?
The most likely answer to this question is the GI Bill. This was the name that was given to two laws passed by Congress as the war was coming to an end. These laws were meant to provide economic help to the returning servicemen, in part so that the economy would not undergo a slump due to demobilization as it had after World War I.
The GI Bill did a few main things. First, it provided monthly stipends to ex-soldiers. They got some pay (around $550 per month in today’s money) each month for as many months as they had served in uniform. Second, it helped them get mortgages for relatively low costs. Perhaps most importantly, it paid for educational expenses. This allowed huge numbers of veterans to go to college even if they would never have been able to go before the war.
Thus, the most likely answer for this is the GI Bill.
