Imo some of you guys are not understanding what the man means by "rent seekers". These are people that simply want to get in the middle of something and produce no extra wealth, only sucking in wealth to themselves. An educator is hardly a rent seeker by this definition, since education is extremely highly correlated to greater wealth not just for the individual, but, assuming she uses her education and doesn't go into a field where there is no multiplicative effect (as the professor points out in the case of some finance and some banking), also produces wealth for society as a whole.
