I think part of the point of the article in the Chronicle is that the top schools will be fine and do not need cut back. While this only applies to the very top schools, they will still have people willing to pay the tuition and endowments large enough to cover any student they want to admit that cannot cover the tuition themselves. It is the small and mid grade schools that may need to carefully look at their models…
I think the real solution is to stop overvaluing university degrees. Most of the folks coming out of universities don't have any particularly valuable job skills. (I'm thinking of majors in business, or liberal-arts fields, or for that matter most people with a BA/BS in the sciences.) Will that happen? Not unless getting university grads gets hard.
This goal should be furthered by private foundations and government. More things should be "priceless".
