I was taking at a private "degree mill" part time classes at $180 per credit hour. The school required 7 students to teach a 4 credit class during normal hours. So at the minimum number of students the school was just making enough money for overhead... Most clases were 10-15 students. It was a private school, so tuition covered almost all their bills, no state funding.
Now ask where sutdents in State Funded Colleges money is going when there are 50 students (and more!) in a class? Where the hell is the undergrad tuition money going if the school only pays "minimum wage" for adjunct or grad school staff?? Where is State and Federal dinging going if Undergrads are paying more than their share of the university bills? It's not gping to TEACHING... And it's not going to "student contact" professors either, and its not "healthcare" or "retirement"... There's a giant money hole in the system.
