In the USA, colleges are in an arms race with each other to attract students. In some ways it is like cities trying to attract professional sports teams or big corporate headquarters: each college tries to outdo the other ones with fancier and fancier extras and services. That results in more administrators to run things.
Ironically, I would prefer a minimal university that only offers education, and not all the other crap, which I prefer to sort out independently in life. Administration is overbloated and needs to be reduced.
