I get your point, I just don't think that "intellectual capacity" is really the limiting factor here. Education is a place where we really can make the pie bigger for everyone I think. And economics isn't zero-sum, we can at least try to make sure people can have 3 meals a day.

Also, I'm not completely convinced of the amount of importance of intellect by birth. But that's more of an opinion I hold, I have no evidence to back it up.
