It seems difficult to teach the hard lessons and experience of personal finance without them actually being hard lessons. Unless something else is driving everyone to accept student loans.
Most of those adults are treated like legal children up to and beyond their first year of college. There's a lot of paperwork adult students can't even fill out by themselves when applying for college until they're 24 unless they've been emancipated.
My SO went back to school for another degree as an established professional, and her university addressed her graduation paperwork "To the parents of...". If colleges aren't even comfortable addressing the people they intend to graduate as independent adults, what opportunities do you see students have in filling that role themselves?
And for some, loans are their only opportunity to attend school. It takes experience most don't yet have to realize that $1000 is a lot of money to spend and not a lot to have. To those, it's. "just the cost of college".
