Misleading Rick.
Those aren't Americans who are fleeing the country to avoid high tax rates.
They are mostly expatriate Americans, already living in other countries, renouncing their citizenship.

Some are, some are not but most still say it is because of taxes. Even your link mentions some leaving because of higher taxes. This seems to be the piece both our links are based on and it mentions both.

Face it folks, our country is screwed up and instead of any of the political types fixing the problems they are all making them worse.
People are fleeing because of high taxes and not just on a national level. They are leaving high tax states too.
Instead of cutting waste, fraud, and over duplication in government they want to raise taxes or cut benefits.
We tax corporations and citizens on money they made overseas and have already paid that countries taxes on.
We have corporations that have to higher lawyers and get a waiver from one government agencies regulations so that they can meet another government agencies regulations.
We have government agencies actively pushing companies to buy cheaper, overseas made products for Medicare patients. You have to be hugely morbidly obese before they will cover the higher cost of an American made product.
We have unions striking because they want to control how many temp workers they can bring in, even if they are not needed.
