Richard D. Kahlenberg: “Harvard picks classes that look like today’s racially diverse America; indeed, most undergraduates are students of color. But the school does not actually reflect America. Research by the economist Raj Chetty shows that Harvard has 15 times as many students from the richest fifth of the population as the poorest fifth.” Freddie deBoer has been great on this for a long time; see e.g. this fiery post.
