This reminds me of that age old question - which came first, the chicken or the egg?
So which came first, the brains or the money? I think strong arguments can be made on both sides of that one. Obviously wealthier nations have access to more educational resources than poorer nations, but there also had to be a beginning to the wealth, right? And if you are smart, and you live in a poor nation (or state if you break it down in the US alone), do you move to a wealthier one for the job and/or resources? So is it the nation being wealthy that causes it to be smarter or the people who are smart moving there for its resources?
Then there's the whole nature vs nurture argument added to the mix. But that's another thread.
