Which Masters Degrees are worth having in this economy?

It has come to my attention that work experience is essential in order to get a job right out of college. People who graduate college with minimal experience or no experience what so ever either are underemployed making not much money or they have no job at all. I know it depends on the major too and the majors that are in this situation mostly are the social sciences. So what happens when you find your self underemployed not making much money like you expected?? You think about graduate school as an option. I am considering a masters degree since i am making 12.00 an hour with a bachelors and graduated a couple month back with a degree in Public Health and a concentration in Health Planning and Administration. Can someone please tell me which masters degree programs are worth having?
