National Guard vs. Part time job to pay off student loans?

Lately after receiving my bachelor's I decided to take a peek at how much I have to pay on my student loans. It was to the tune of 60k interest included roughly. I do plan on continuing on to receive my Master's in Social work but with this amount of debt and the Master's degree isn't going to be a walk in the park I decided to check out the National Guard since you hear on the commercials that they have loan forgiveness programs that will pay up too 50k or so and they'll pay full tuition since I am in New York that's the deal. But when you break down the benefits. Say for the sake of argument that I do in fact receive the full 50k of the loan repayment and help fund school. You will have to enlist for 6 years to get that high number so the math (50k/6=8,333.33 per year before taxes) and plus the tuition for a master's degree. With a part-time to full-time (working summers) position you'll be able to make 17,000 - 20,000 a year. How do the "benefits" the guard pushes worth it when you could earn more as a civilian and don't have to risk going over seas? Please no bashing and comment's well you shouldn't join if you are doing it for the money. But you should not do any career if you do it for the money. I could live my dream and flip burgers all day but then I would just be getting minimum wage and have a shitty life. so you have to think if what you do actually pays. Sorry this is long but the details are needed thanks!
