>Also I am sure the janitor at the University is paid decently and loves to work there. Reason is there are not as many people lined up for that job and basic economics takes over.

Janitor and other unskilled labor jobs at public universities tend to pay crap but are highly sought after because they usually come with the union negotiated benefits package that makes them a better value (than local work in private industry for more money and less benefits) for many people.

Back when I was doing those kinds of jobs I wouldn't even think about wasting my time working for a public university but I was young and needed the money more than I needed healthcare and 40hr weeks.
