A big endowment ($13.5B / class size = 940 => $14M/student) + the will to use it on scholarships. Kudos to them. I did undergrad at WashU, which in this ranking is the poster child for regressive admissions. WashU is opposite MIT in this respect: a medium-sized endowment ($6B / class size = 1400 => $4M/student) and no will to use it, at least not on scholarships. It was not that way back when I attended. The only way I can make sense of the graphs of diversity vs. time is that they are aggressively increasing tuition, recruiting among the wealthy, and erecting fancy buildings.
