Earlier quoted context omitted.
Do you have a source for these numbers? $100/hr is highly suspect for "students that graduated last year and were helping out as teachers".
I had a family member working at the school. She knew all the salaries. I was often asking, and getting heart attacks when crappy teachers were getting paid 300$ /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.
