Just read the above the other day, and I know it's slightly off-topic, but it meshes nicely with some of the points you made.
I figured out around the last year or so of my university career that I should have actually spent less time in class than I did, but I did eventually figure it out. And I agree wholeheartedly with no one explicitly telling students about all of this. I can't tell you how livid I was once it all clicked. I try to expose the idea to as many high schoolers as I possibly can, but they aren't yet affected so it doesn't exactly make a whole lot of sense to them.
Anyhow, this comparison of student loan / universities working as a new profit center, similar to the junk mortgages of the '08 crash is new to me though. I think it illustrates what's going on very clearly, even if Micheal Hudson is a bit extreme with his view of the schism between public/private.
Jane Jacobs also wrote critically of what Universities had become (credentialing), and how it might (negatively) affect our culture sometime down the line in her book, Dark Age Ahead.
