I's bet that the actual teaching at "lower ranked schools" is already as good as that at "top tier academic institutions", but to be ranked as a top tier school would probably require it to tow the leftist line in every way.
I taught the same class at GMU that I did at University of Chicago. It was the Management faculty that was huge and terrible. Lots of propaganda (left of course). Easy A’s. They teach “strategy” and “how to be a CEO” by people who have never been CEOs or even worked in the private sector.
