Re: China will become Super Power ?

China has a major demographic problem because of the one child policy. Soon, it will have too much old people, a lowering of its active population and growing problems, just like Japan and now Europe.

Who knows what will happen 30 years from now? We could have immigration from other countries into China.

I would find this somewhat unlikely. The standard of living of people living in China is really not that great. They also are lacking many rights that 'free' people generally take for granted (freedom of the press, uncensored internet, ect)

They did make a big jump from communism to pseudo-free market.
So I guess change is possible.

I would say that China is still very far from being a free market. They have strict currency controls and keep their currency almost pegged to the dollar (They allow for small fluctuations on a daily basis). They also restrict the flow of ideas, information and speech. See the GFW and the recent blocking of bitcointalk.org from inside most of China
