Earlier quoted context omitted.
To be clear, I don't think college should be paid for with loans. I agree with you that we shouldn't be enslaving people. But I also don't think allowing these loans to be discharged in bankruptcy will solve anything (and will arguably make things worse) without systemic changes in the way college is paid for.
It will force "the system" to come up with some other way to pay for tuition. What do you think about Income Share Agreements? https://www.thesimpledollar.com/loans/student/income-share-a...
Note that "projected lifetime income increase" is generally overestimated. What we do is compare average income of a college graduate with a high school graduate and attribute the difference to college. However people who could get through college likely would have made more than people who couldn't, even if they hadn't gone to college!
