I missed Australia. Taiwan and S. Korea are 2nd world.
2nd World? So they're in the block of socialist/communist economies run by the Soviet Union? Which is what 2nd World means. First world was the US and its direct NATO allies, 3rd World were the underdeveloped mostly neutral states. If you're referring to economies, S.Korea and Taiwan both have mature manufacturing economies and most of their people have a relatively high standard of living (purchasing power parity) since a dollar doesn't spend the same everywhere.
