I also wonder why China suddenly went from a purposful wreck of an economy to a techie powerhouse in ~20 years.
It's more along the lines of 40 years rather than 20.
China's economy improved because Mao died, and everyone was very happy to do away with the principles of the genocidal lunatic who killed millions and millions of people over the years, though they did do away with those principles in his name at first to placate what loyalists he had.
They also broke ties with the economically stagnant USSR and therefore by definition were immediately our best friends. It just goes to show, not even schools of thought that are radical even within Communism could make Russia and China like each other.
A stronger Chinese economy is good for the United States. A stronger U.S. economy is good for China. I don't like either Romney or Obama bashing China for political gain. Mostly, they seem to be trying to one-up each other on being anti-China. In the last debate though, Romney brought up his promise to declare China a currency manipulator on his 1st day in office. Obama responded, correctly, that the Yuan has been going up, not down, versus the U.S. dollar.

It means their goods would cost less. This is bad for businesses competing with Chinese exporters, but it is good for just about everyone else. If you were buying something from China, and the Chinese company offered you a 10% discount, would you say "No thanks, I would rather pay more?"
The ones helped most by a cheap Yuan are the poor. If I have to pay a 5% or 10% more for something from China, it won't affect me nearly as much as it would affect a poor person.
Anyway, it is not a zero-sum game. People seem to think that the better China's economy does, the worse it is for the U.S.
Also, the more dependent on each other's economies the U.S. and China become, the less the chance of a military confrontation.
China has come a long way in moving toward a capitalist economy (that's good, by the way). But they still have a long way to go in regards to individuial freedoms. I believe that, as their middle class continues to grow and become more affluent, they will demand and get more individual freedom.
By the way, having seen the future, I recommend you buy YINN. It's going to triple in the next two years.
