The US taxes citizens on world wide income, no matter where they are resident, so they are probably the worst choice among the first world nations for the super rich. There are people, like Eduardo Saverin, who give up their US citizenship to avoid US taxes.
The UK is a haven for a lot of these people, as it has a very attractive non-domiciled rule (live in the UK, only get taxed on UK income or income which you bring into the UK - income which stays out of country is effectively untaxed).
Or, perhaps a jurisdiction like Hong Kong with no capital gains tax might make sense.
