Over the past generation the Chinese system (socialiism with Chinese Characteristics) has ourgrown western capitalism by at least a factor of 2 so why should China wish to decline into US style capitalism?
On the contrary, unless the US pulls out a finger in the next decade, it will have to emulate China rather than vice-a versa. In this case, the US maxim. (you dont fix it if its not broke) applies to China, IMO
