So finding someplace along one of South America's coasts would be attractive. Australia would be extremely attractive if we could get automation right because labor costs there are just too high. Africa would also be attractive in the extreme. You wouldn't even have to take the resources off of the continent. Lowest labor costs around. Plus, two enormous coasts full of warm water ports.
Anyway, the idea would be to set things up so that if one region goes to the dogs, you just switch to the other.
EDIT: Now I think about it, there are some pretty large political issues in africa right now, so maybe africa wouldn't be the best place. Populism could easily end up landing you in the same situation as white farmers in Zimbabwe. Anyway, the fundamental idea still stands. Balance manufacturing from Asia and N America more towards S America, and Australia.
