As soon as I saw the headline for the girl accepted at all Ivies I thought "Nigeria. Igbo." The Igbo are called "the Jews of Africa," an historical trading people who know multiple languages and moved easily between groups. Smart people. In America, they get the benefit of affirmative action, because the Ivies don't generally want to take inconvenient black people, preferring to skim the cream of the African elites and the Deltas in America. From this perspective, they then call other Americans racist, which is infuriating.
If you doubt my assessment, you might notice that last year's "all Ivy acceptance" high school senior also has Nigeria prominently displayed in his autobiography.
Bright kids, I hope they go far, and choose fields other than racial grievance. I'm not a believer that having a hero out there actually does change things that much for kids. I think it's a post hoc rationalisation. But for those of you who subscribe to that, pray that they go into chemistry or philosophy or evolutionary biology or something.
