I've actually been thinking about how to set up a shell corporation for a completely different reason. If the U.S. (where I currently live) fails, how do I operate a legitimate business? If I'm still living here, I should pay taxes here but if I choose to relocate, why should my entire financial infrastructure have to change? On the other hand, if the economy fails it could very well take me with it ... I guess if I have to start over it doesn't matter where those accounts were.
