Does Chinese growth threaten US leadership?

What difference does it make for the average American? Has America being the wealthiest mean that this country has no unemployed, full employment, health care for all and no homeless? Not only that, maybe it's time that the US begin to attend to its own affairs. And as for influence, yeah, the Chinese may become the most powerful economic country on Earth, but culturally America will still dominate. How many people on planet Earth are clamoring to live under an autocratic dictatorship like China? Why do you think people all over the planet STILL clamor to live and work in the US? I haven't spoken to anyone who wants to live under Chinese rule, least of all most Chinese citizens! And don't even get me started on what groups like the Tibetans, Uighurs and Taiwanese think about the glorious mainland Chinese. Economic power isn't everything. As for military power, don't worry about it. So long as nukes exist the Chinese won't make a move. If anything, they'll take over the US like the Mexicans are doing - by giving birth to millions of anchor babies b/c the US Congress is too stupid (sinister?) to amend the Constitution to limit US citizenship to those born in the US who have at least one parent who is already a US citizen. In any case, if the US goes down, it'll be b/c it's citizenry was content, and actually encouraged, corporations to control its government.
