But that is true of everything we do loans for, nowadays. The amount of consumer debt that people contort themselves into justifying is insane. If you want to use that as evidence that grade schools are failing in education, I can largely agree with you.
I can largely agree that it, similar to other things, has become too expensive. I cannot agree that it is not worth it for folks that can do it.
Totally inverted? Of course not. But there is a very real portion of individuals for whom debts exceed earnings and it is very much in the data. But if you want to ignore reality to win on semantics go right ahead.

Again, I can agree if you are claiming it is of diminishing benefits. I'll go further and agree that there have been predatory practices to get people to take out loans they shouldn't take out. This is directly addressed by your source. Which, notably, still supports that people have higher incomes after graduation.
What I cannot at all agree with is it being "inverted." Nor can I agree that they are failing to educate people. By the stats I have seen, this just isn't the case.
