How do we help those kids that are in 'gen pop', though? Simply pulling the smarter kids out, helping them, and ignoring the rest doesn't seem like a good answer, either. I feel like HN is not the best place for this sort of discussion, since everyone is coming at the problem from the perspective of the high achiever. The low achievers deserve help, too.
You can probably get good milage out of recursing this up until the point you're dealing with fractional people.
