On: Wealthy people are renouncing American citizenship

I would suggest that the major benefit would be that if things go to shit wherever you are, you can flee back to the US. There are probably other countries you could choose for that instead, though.

Also, if you give up your citizenship, does that have any implications for traveling back to the US? You might very well have friends and family you would like to visit occasionally.
