That’s all well and good and I’m glad you’re happy, but the real opportunity for going expat is in the developing world, I think.
I met a guy from NYC a few years ago who had worked in advertising and marketing on Madison Avenue. When Vietnam opened up, he moved over there and started a marketing/PR/ad firm over there, and got fabulously wealthy just by doing things that were basic blocking and tackling over here, but unknown to them over there.
I lived in India for awhile and would go back in a heartbeat; the exchange rate would have us living fabulously wealthy. Other good places where your money goes a long LONG way: Kuala Lumpur (beautiful, civilized), Bucharest, Greece (not as cheap as the other two, but once you get off the beaten path a bit, still big bang for your buck.)
