The US is, by and large, successful because we have the largest market in the world (forgetting for a moment the effects of WWII). We continue to be a success because we have a huge population of affluent people who can spend enormous amounts of money on consumer goods. The Chinese middle class is already larger than the entirety of the US population* and will continue to rise as the country increasingly becomes a first-world country.

There are of course issues with managing such a large population, but the chance of any sort of collapse is the figment, and hope, of our pride and does not reflect the realities of the situation.

* - Income of middle class in the US is higher, but cost of living is also substantially less in China.
