Back to college-- when I already have loan debt?

So here's the deal... I'm 35, and I have about 40,000 in debt for a B.A. in political science (pretty much worthless, but earned summa *** laude thank you very much). Since I am having trouble find a good job, I am thinking about going to a community college to get two associates degrees: one in accounting and one in CIS--database analysis. For both degrees, I would have to borrow another 20k, meaning I would have a total of 60,000 borrowed. My thinking however, is that the increased debt would be more than off-set by the increased job opportunities and pay in just a few years. Suggestions?
