I started to respond to some of these comments, but they are just too poorly thought through to even try to explain it.
Instead I will just say that the United States has the best universities in the world, and doing something that would jeopardize that status would be dumb. There may be a point that top universities should spend a bit more of their endowment money year to year and hoard less of it, but it would be dumb to do anything harmful to these schools.
