My reply was somewhat tongue in cheek. These institutions are not liberal. They do more in America to serve the status quo than any Republican in the John Birch Society. First of all, their legacy programs that have preferential admissions for donors and sons and daughters seem to insure that the same type of people are getting in from year to year. Sometime up to 40% of a freshman class is from the Legacies, so that leaves 60% trying to get in competitively, and those that get in based on merit have already attended some of the best high schools
I wonder how many Orchard Park grads get into Ivy league compared to Niagara Falls. I would bet big bucks it would be OP, so there is an economic filter to live in the places with the best high schools that would prepare you to get into a Harvard, or a Yale.
The Ivy League is Status Quo.
The arguments against affirmative action rarely include discussions of legacies which is an embedded affirmative action for the rich.
