I think when we’re speaking of a societal issue like “the student loan crisis” we are more interested in the totals borrowed than the per-student amounts, which I didn’t see in that report but I didn’t get to go all the way through before I posted it.
I haven’t been able to find what i was looking for, which was the flat “what is the total amount owed by public vs private nonprofit vs for profit” figures. (back in the OP the assertion was that it was public but I haven’t been able to find out one way or the other).
