"If you're going to compare a middle-income black kid with a middle- income white kid, and, say, you control for family background, family education, and family income, and if this middle-income black kid doesn't score as well as the white kid on the test, then I say, look, you haven't taken into consideration the cumulative effect of living in a segregated neighborhood and going to a de facto segregated school. You're denying a position at Harvard or some other place to a kid that really could make it. That's why I support affirmative action that's based on both class and race."
