Oh yeah, right. By some miracle of education is different from every other market system. That's worth studying.

All I have is anecdotal information from the town where I work, in which university coaches get paid a hell of a lot, engineers get paid less (but more than most profs) and most of liberal arts is taught by part-timers (euphemistically labeled, "adjunct" to take the sting our of it). I'm sure liberal arts profs at other schools are held in much higher esteem than some backwoods diploma mill like mine.
