How does that happen? I come from a time where my private university tuition (before grants, financial aid, etc) was around $25k/yr, and I understand things are different today.
I don't know all the ins-and-outs of today's student loan options, but say that 120k is taken at 5% spread across 20(!) years, the monthly payment on that kind of loan is around $800/mo. Did this person not have a clear idea of what recent college grads with English degrees make? I mean, it seems like a serious misjudgment to bury themselves in that much debt without a very clear path out of it.
I'm not suggesting the "learn to code" or "only STEM degrees matter" trope, but if you really want to become a writer, or a teacher, or anything else where an English degree is required, you can get that at a much more affordable price: I know someone from a "poor" family who did exactly that, but went to UMass Dartmouth and now has a successful, average middle-class life as an editor. They did not need to go to six-figure debt because they knew they would have a really hard time paying that off...
