So when someone leaves an area of low tax/education to high tax/education, seeking economic gain, it's called brain drain. What is it called in this case when it's reversed?
I don't see what's all this fuss about, it's just simple tax "planning" as exercised by the wealthy. I guess the extra billions will make him happier, but it's weird we get attached to such things as money when you have already amassed it so much it doesn't really make a difference.
