I'm all for widening the world and all, but let me think out loud. Harvard lets really brilliant people meet each other in a place that offers exclusively brilliant people. (Brilliant by Harvard's standards, anyway: I'm aware that that's not a perfect standard.) It gives them some world-class teachers, and it gives them class sizes small enough that students can build relationships with those teachers. How do you lessen selectivity without also lessening the experience of being in such an exclusive place?
