I can't really say except that obviously non-ALDC white students are a much smaller proportion of Harvard's class than undergraduate students overall. My guess is that they have target numbers for diversity. Since the overwhelming majority the ALDCs are, due to economic and historical factors, white, it is quite difficult to get into Harvard if you're white and your parents didn't go to Harvard, dont' work at Harvard, aren't rich enough to make a big donation, or aren't moderately wealthy and savvy enough to get you into some obscure Harvardy sport like rowing.
