I think wealth correlates with opportunity and education. People in predominantly African and South East Asian countries are disadvantaged in this sense because a large proportion of its citizens cannot afford good education. Likewise, the cyclic and low economic state of each consecutive generation contributes minimally in terms of education, nutrition and general industrialisation of the country, factors which directly one's ability to obtain "wealth". Many people in these countries probably have higher IQs than you think, but majority do not the get the opportunity to apply this to a "wealth-gaining" profession.
