I think it's less about the amount any one person is paid and more about the huge number of administrators moving paper from one desk to another.
I went to a private liberal arts college with a few thousand students. We had a Dean and four assistant Deans, all of whom made multiple six figures a year. Our president when I was there made $450k/yr and had next to no living expenses.

Private v. public has nothing to do with academic bloat.
But Big 10 football (and basketball) runs at a profit for the schools, it's the big salaries at smaller sports programs that don't make financial sense.
When academia is run as a business and subsidies are drastically cut, you need to devote resources into acquiring new customers, which means competing with other universities who are doing the same thing. Hence the rapid increases in campus amenities and business administration positions that never existed 30 years ago.
> campus beautification projects like replacing the flowers every month
Out of all things to complain about, flowers on campus are on the low end of the totem pole. Let them plant flowers, I say! I enjoy them.
You forgot paying for sports facilities...
Edit: Downvotes for wondering why universities are paying millions for sports facilities. Nice.
