I'm very skeptical of the claim that most of the kids with good parents in your poor neighborhood ended up in the 1%. Even with good parents, kids can grow up to be dumb and poorly socialized.

Also, "poor" as you're using it here might be too broad a term. The amount of brain cycles that parents can spare for their kid's academic performance is inversely related to how much time they're worrying about food, whether or not the utilities will be shut off, how to work overtime and keep the kid safe, etc.
