The IRS taxes americans no matter where they are or where they take their money. The US is only one of two nations in the world with citizenshp based taxation. And if you want to renounce your citizenship, 35% exit tax. The only solution is to make a foreign corporation (Apple keeps its income in Ireland for example) and hide your money there (The City of London does a brisk business setting up corps in their old colonies - when the IRS comes knocking, the City of London plays dumb)
