Once tariffs are lowered the entire thing becomes based off of labor costs and transportation costs, Since the Baltic Dry Index is at an all time low it means it's just based off Labor costs. The country with the largest population will grow exponentionally while the countries with the lower populations will stagnate, also depending on level of development. Once a parity in economic status is reached, the next recipient country will be the one with the larger workforce pool, this is why it has first been India and China. Next it will be africa and the Middle East or Russia

@ George: WTH does technology have to do with lowering tariffs and allowing cheap imports to flood the US market causing massive destabilization and the lowering of living standards?, This could have been done in the 1800's, wouldn't have mattered what technological era it was in. Yes you could say well the Chinese just got advanced industrial technology blah blah blah. true but they still wouldn't be able to supply the US economy on the basis they are now without the reduction of tariffs.
