If the the economy in America is so great, then why are so many Americans moving to China?

You start from something to become great in time. Some take 100 yrs others 200 yrs as in USA and China took few thousand years to be as at present. In real sense, it took around 30 years to upgrade their development to this modern situation and is still just behind others in many area.......like internationalisation in concept and acceptance. For the EU & USA it is a great opportunity for them to venture into China as well as India to find their chances of progress into a world which is slower than theirs. The world is a place for each other to learn from one another to their best benefit and value the opportunity to try it out. The Earth is turning and for the next 50 years it is the East to show the WEST that they are going down in time.
