Most student loan debt is “government” backed. When default occurs the Treasury gets involved and heavy garnishment ensues. Doesn’t matter where the borrower goes job wise, the Treasury will find and garnish them.
I ran across one young woman who was 130K deep in student loan debt. Her “degree” was in some sort of “studies” which basically meant there were really no jobs for her (her fault BTW)..
The loan I could see getting is to complete a 1-year or so program at a technical school, and be employable. Then, when that's paid off use money made working for college courses.
