The research substantiates this thesis though. As cited variously in grandparent threads, domestic environment and culture are the main predictive factors of academic and economic outcomes. Poor kids who study do much better than rich kids who don't.

We no longer deny people opportunities based on their race. If your SAT score is high, you'll be admitted anywhere you want. If you study hard, your score will be high. The reach is constructing the SAT, or any other similar test, as racist because the scores are not evenly distributed by race.
