I can see a huge business opertunity for lower ranked schools to become top tier academic institutions by recruiting competent non DEI professors and teaching intellectually rigorous courses on subject that matter. Some math and science may be required.
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.
