■"Study Finds Small Developing Lands Hit Hardest by 'Brain Drain,'" by Celia W. Dugger, New York Times, 25 October 2005, p. A9.

The brain drain happens to states where there is no economic opportunity to keep people home. These places don't have to be rich, just full of real opportunities. China and India and Indonesia and Brazil, all big teaming New Core pillars (Indonesia right on the verge), they don't suffer this even as all suffer big chunks of their population still mired in extreme poverty.

The brain drain is not a cause of poverty but a symptom. Establish enough vibrant economic connectivity with the global economy and your people stay home. Everyone really wants to stay home.
