He has railed against the 1960s Cultural Revolution for years. Its roots, as he said in 2017:

"First, the major American colleges, run heretofore by WASPs, opened their doors, after the Second World War, to all sorts of people—first, Jews. A decade later, blacks and women. Jews were admitted as students, then faculty members, finally bosses—deans and presidents. Naturally, big changes resulted. College faculties were left-leaning anyway, but a significant Jewish contingent made them even more so.

"Second, a growing belief that college, like high school, was good for everyone—and the “professionalization” of all sorts of fields where a BA used to be plenty: the rise of business schools, the growing importance of education schools and of journalism schools were three of the most important aspects of this big change."
