I had one professor in college who made most of their money by forcing students to buy his book (it was an ebook so it couldn’t be resold, and also super expensive, and the class homework was all linked to from the book itself). The class was also somewhat useless, which lead to a lot of students surmising that the professor’s deal was basically just <pay book price> = free A / course requirement lol

This is a return to the original model of a university, where professors made their money from the course fees students paid to take their courses.

It's an improvement over what we have now.

Are you sure about that?
