I live in a $3 million house and would be COMPLETELY OK with my kids being rejected from their dream schools for poverty-linked affirmative action. They have a vastly easier path to academic achievement, and if they got 90 points on a test and a poor kid got 80 points, that other kid just plain old outperformed them.
You'll find a lot of us out there who are vehemently opposed to race-based affirmative action but would enthusiastically support wealth/class-based affirmative action.
