The correct answer is the GI Bill.
This law helped veterans returning from service in World War II in multiple ways. One example would be funding for veterans education. The GI Bill paid the tuition of thousands of American soldiers to pursue college degrees, resulting in a highly educated workfroce.
Besides college tuition, the GI Bill helped veterans to gain access to low interest home loans. This allowed thousands of veterans to afford new homes in the growing suburbs of the 1950's.
