Opportunity cost. Not making that risky but high upside potential career move at 26 because you have a $1k/mo debt payment to make is going to severely impact your total earnings far more than any other time of your life.
The advantage of youth is mobility, flexibility, and ability to take on risk. You give a lot of that up with a high debt load at that age.
Besides, in the U.S. a great generational theft has occurred. The older folks benefitted from much higher public support for their higher education. Now they vote to defund higher education and this has led to penury for large numbers of recently graduated college students.
Yes, it was not a great argument for spending a trillion dollars on student loan forgiveness. Mostly I was pointing out how out of whack the moral priorities of the U.S. are. There is very little debate or angst over spending a trillion dollars on a useless war. But somehow spending a trillion dollars on student loan forgiveness makes everyone think about moral hazard. You mentioned morality and so I took things a bit further than what you did.
I don't see how advocates for this policy can escape that logic without declaring math irrelevant.
