I'd argue all of those areas you list are far more likely to be improved over the course of a lifetime than sheer intelligence. Pure intellect is pretty much set at birth, or at the least the ability to improve it isn't statistically significant. I'd argue that genetic dice roll and environmental dice roll are quite different things as well. You have FAR more ability to change your environmental situation than your genetic one. Does everyone have an equal chance to alter their environment? No, but who said life is fair?
