It seems to me that in economic theory, capital should move around and people should stay at places. It would be rational and also it makes sense from human perspective (you're close to your family, you don't have to deal with the logistics of moving etc.). However, in economic reality, quite the opposite is often true. Capital doesn't flow into underdeveloped regions even if they contain great talent. And people try to migrate, in fact so much that some think it's actually a threat. Ha-Joon Chang's "23 Things about Capitalism" has a great chapter on capital not being that international (that is, interchangeable) as people typically think.
