These 10 graduate degrees do not really help you earn more

Employees armed with a graduate education are often a more attractive hire and can make a higher salary than colleagues who have only a bachelor's degree.

However, for some industries the benefits of going to graduate school are comparatively low and don't justify the extra investment.

Using the recent "Hard Times" report from the Georgetown Center on Education and the Workforce, we examined salary and unemployment data of experienced college graduates and experienced holders of graduate degrees. These are workers whose ages range from 35 to 54.

For roughly 50 fields, we calculated how much more money a graduate degree would bring and the difference in unemployment rates for those with a post-college degree. These figures were then combined to determine which graduate degrees were the most "useless" — basically, which give you the smallest boost in salary and employment.
