Well professors are paid a lot more than they were in the 50’s, 60’s, 70’s too. Room and board costs a lot more. Books are 10x as much as they were. I had a book that cost $16 and it was published by my uncle so I made him send me a copy because it was sooo expensive. Now? I’d be thankful the book wasn’t $125.
My tuition my first semester was $350 and that included books. I think room and board was about that too.
