I would categorize them. Science, Medicine and engineering will always pay off. I would imagine most of these people will have paid back their loan within a ten-year period or less.
But roughly sixty-percent of the degrees? You would have to anticipate 20 years to pay off $100,000.
I worked with an idiot who had a degree in TV production...out-of-state school, so she paid an enormous amount of money. Even at age 35, she was still calculating another 12 years before the final part of the loan was wrapped up.
The whole system needs to be rebuilt, and limit your loan to $10k a year max. Let the college figure out their own path to cover the cost.
I humbly suggest that the issuers of student loans be allowed (even encouraged) to discriminate strongly according to the student’s chosen major. For some programs of study, getting a student loan should be impossible on the grounds that it will never be repaid.
