They absolutely understood the terms of the loan. I think they do it anyway because: (1) everyone else is doing it and they don’t have a good alternative (2) career optimism. If you end up becoming a lawyer/consultant/accountant or otherwise have a good corporate job, in the medium-term your student loan debt doesn’t really have a significant impact on your life.
It’s really only a problem if you (1) choose a private college and don’t stay in-state, (2) get a degree which doesn’t have a lot of practical value, and (3) then want to pursue a low-paying field or get a not-useful graduate degree. For example, a friend of mine did her undergrad in art history, master’s in museum studies, and works for a non-profit. She’s not rich but she’s able to survive reasonably comfortably. She’s not dumb or financially illiterate, and she knew what she was getting in for.
