1. If the US defaults, what country can I move to that will substantially increase my odds of success?
2. If fiat currencies hyperinflate, [same question]?

1) doesn't hold US debt and does not do substantial trade with the US (sorry Canada, Japan, Mexico, et al)
2) Has large reserves of gold, petroleum or industrial minerals.
3) wants skilled English-speaking immigrants
... that leaves South Africa, Brazil, and... maybe AU?
