@DrewDad,
I agree with that. When i worked there, the University of Illinois failed 50% or more of the incoming undergraduates every year. There was a very stiff competition among graduate students for teaching assistant positions, just because there were so many of them looking for a job. I knew a guy who was in the philosophy doctorate program, who got an assistantship one year to teach astronomy, about which he knew squat. I was talking to someone once when he was there, and this guy asked me what the speed of light is--and i told him it's in excess of 186,000 miles per second. This joker who was teaching astronomy interrupted to say: "No it's not, it's 186,000 miles per
hour." I told him he was wrong, and even eventually pointed out that if that were true, it would take more than an hour for a radio message to go one way between the earth and the moon, which is about 230,000 miles away. He denied that! Why was a guy from the philosophy department teaching astronomy? Politics.
They guys who had the cushiest berths were the research assistants, and there were lots of those at the U of I, a major research institution.
I agree completely that many large universities are money making machines, and teaching is at the bottom of their list of priorities.
