I had a family member working at the school. She knew all the salaries. I was often asking, and getting heart attacks when crappy teachers were getting paid 300$ /hr.
I am also not familiar with for-profit universities though, which it sounds like maybe yours was?
I am still sort of thinking that something got misunderstood on the way from the family member sneaking peaks at salaries in the office, to you, to us.
My university was for profit, as I said it's a french based university. The director owns multiple Lamborghinis (not sure although if it is related to being for profit).
My family member was not sneaking peaks at salaries, she was the one hiring the teachers, signing contracts with the teachers, etc...
As everyone who has done any teaching knows, the time spent standing in front of a class is just a small part of the total required time.
