The US is no “tax haven” by any stretch of the imagination, but the more important point is that wealthy Hollywood types and business tycoons have the capacity to choose where they want to live. The rest of us don’t. The same goes for US States. Businesses and the wealthy will move to where they can keep more of their money and generate the best returns on their investments. Note the case of Maryland and Virginia, two states that have seen tax and regulatory policies diverge in recent years.
