I'll partially agree with the money piece.....I meant to touch on that before. Surely the schools make money but that varies wildly by conference and school. HOWEVER, regular students as you call them can generate cash as well. I went to a school where the student researchers generated far more cash than the athletic program. And most of the researchers were not on scholarship. And many were working 70-80 hours a week just in the research labs. I slept in my lab many many nights. Never got a dime from all the patents, consulting, federal and private grants. Not one dollar.
All I'm saying is there are no absolute statements.
I was not a scholarship athlete but most of my friends were. I didn't wear their shoes but I have perspective.
Did the researchers on scholarship risk losing their scholarship if they let someone buy them lunch?
