The western world had pretty much the same situation in the 18th century. Lots of lowcost labor in dirty factories.
China will get were we are in much shorter time, but who will do the cheap stuff then?
Big problem in the long run is all the money we send them, the only thing we can sell back is real estate.
They will conquer the world with money instead of nukes.
What if they buy the rest of the world and we all become chinese
