in 1980 how much more money did workers with a college degree make per hour than workers with a high school education only?

According to the Economic Policy Insitute (EPI), the gap in hourly income between college graduates and high school graduates was approximately 40% in 1980. However, this gap was increased in the forthcoming decades, reaching 51% in the year 2000 and 56% in 2015.

One reason for this is the decline in manufacturing jobs, as many factories were moved overseas due to production costs. These jobs could be occupied by high school graduates. However, due to the reduction in job offerings for this sector, these workers have shifted to the services sector, which offers lower hourly wages in comparison manufacturing.
