I agree with Ozy on this one. I think the creativity and capability we have is universal, not stronger in some than others. Look back at an anthropological history of our species. Cave paintings, bead making, stone crafting, dancing, these things predate language and writing. Even speech is believed to have started out more as singing and eventually was simplified as a form of daily communication. Scans of the cranial cavity in Neanderthal remains has suggested the formation of their frontal cortex and speech centers might have been more adapted to song rather than speech.
As I stated earlier the biggest problem is shear number. It is hard for all people to be given the opportunity or accessibility when population density is high and resources or few or badly distributed. However, as education becomes more accessible we see the positive results.
Economically we see stabilization and greater community contribution. We work together to overcome hardship rather than tear each other apart (sorry doomsday prepers, but evidence shows that we are more likely to work together in bad times instead of killing each other for supplies. Exp- Super Storm Sandy). Education becomes even more accessible and as that opens new opportunities for people to specialize than we see greater attention to our careers and social circumstance; this generally reduces birth rate substantially. This is why we see fewer native Europeans being born in their own countries than we see immigrants or white people in the US. The greater the resource cost and educational expectations per child, the more cautious people will be to limit how many they have. Also access to birth control, etc etc.
Point being, as we become a more evenly educated society than the more our numbers and use of resources will stabilize. Now there are still cultural issues to work out of course (those that demand greater numbers of children to be born or limit/deny the use of contraception) but as we become more educated these older social norms begin to die off.... hopefully sooner rather than later.
