[lbo-talk] stats on profs' class background?

[Stephen E Philion]

Anyone know some good sources on class backround of profs, especially
left leaning profs? On the Marc Cooper discussion blog, he and others
are trying to claim that professors who are left leaning are mostly
priveleged wealthy elitists with no working class background to speak of. 
Of course, that they are mostly still working class, tenure, perks and
all is a point entirely lost on this kind of person...
