Ever listen to Dennis Prager? He has an axiom that the more education, the less "smart" the person becomes. In his way, he believes that higher education warps and destroys the wisdom gained in life experience, and replaces knowledge with pablum. It is on here when Rush is, so I listen daily.
Dennis is very good, and usually correct. I would rate him in the top 4 radio talk show hosts, ahead of Medved and behind Hewitt, and of course, El Rushbo.
