Americans renouncing citizenship

A number of recent articles covering the prospect of Americans renouncing their citizenship has caught my attention and left me wondering.  Bermuda could be ideally placed to capitalize on the these sorts of moves if it were more open to a Monaco style residency model.

Would it enable us to attract wealthy individuals, their business and investment while offering possibly one of the best locals for continued access to the United States?  What impact would it have on getting our economy back on track?
