Simple.. we're the largest ethnic group in the world and one of the fastest growing economies. Fast economic growth + already dominant population = WIN.

I believe its the other way around. Without chinese investments the US economy would collapse, its the only thing thats holding it afloat (thats why china is not a rouge nation nor a country who supports terrorists, but they are and they do). Yet, the current situation is unstable, something have to give one way or another and that will prolly suck big time for the US when that happens.
