He has some interesting statistics about college and class:

On the surface, it looks as if things have changed. Compared with 50 years ago, the proportion of students coming from old-money families and exclusive prep schools has dropped. The representation of African Americans, Latinos and Asian Americans has increased. Yet the student bodies of the elite colleges are still drawn overwhelmingly from the upper middle class. According to sociologist Joseph Soares’s book “The Power of Privilege: Yale and America’s Elite Colleges,” about four out of five students in the top tier of colleges have parents whose income, education and occupations put them in the top quarter of American families, according to Soares’s measure of socioeconomic status. Only about one out of 20 such students come from the bottom half of families.
The discomfiting explanation is that despite need-blind admissions policies, the stellar applicants still hail overwhelmingly from the upper middle class and above. Students who have a parent with a college degree accounted for only 55 percent of SAT-takers this year but got 87 percent of all the verbal and math scores above 700, according to unpublished data provided to me by the College Board. This is not a function of SAT prep courses available to the affluent — such coaching buys only a few dozen points — but of the ability of these students to do well in a challenging academic setting.
Far from spending their college years in a meritocratic melting pot, the New Elite spend school with people who are mostly just like them — which might not be so bad, except that so many of them have been ensconced in affluent suburbs from birth and have never been outside the bubble of privilege. Few of them grew up in the small cities, towns or rural areas where more than a third of all Americans still live.
