What you don't like paying for college campus admin overhead ? Lush green gardens for students to admire?

Interestingly, increased spending has not been going into the pockets of the typical professor. Salaries of full-time faculty members are, on average, barely higher than they were in 1970. Moreover, while 45 years ago 78 percent of college and university professors were full time, today half of postsecondary faculty members are lower-paid part-time employees, meaning that the average salaries of the people who do the teaching in American higher education are actually quite a bit lower than they were in 1970.

By contrast, a major factor driving increasing costs is the constant expansion of university administration. According to the Department of Education data, administrative positions at colleges and universities grew by 60 percent between 1993 and 2009, which Bloomberg reported was 10 times the rate of growth of tenured faculty positions.
