I may be missing something, but I don't see anything in either of those figures that rules out people who leave school after one or two semesters, or otherwise don't graduate for some reason. Maybe that's intended, but I feel like it'd be useful to include the average amount of debt of students who graduate. For my state (PA), it's at almost $35k, but only 71% of them have any debt at all [1]. That means that $35k is calculated with 29% of the values being zeroes. My degree wasn't in math, but I think that means that if you graduated with any debt at all in PA, you've likely got $50k or more. Does that mean it's a bubble? I don't know. I do know when I was an employee of a private university in PA, we were told year after year of 4% tuition hikes while being told we should be patting ourselves on the back because it's below the national average. That definitely sounds unsustainable, but so far it's been working out pretty well for colleges.
