For the hyperrich, setting aside 10 or 20 admissions for "idiots who bring new science buildings with them" seems to benefit literally everyone at the school.
It's over 200 out of about 2000 at Harvard, plus another 200 for athletes... Though of course the bigger issue is that Harvard only has 2000 places for undergrad despite a $50bn endowment, in order to create some artificial scarcity.
