That's a low grade racism. China has issues, but is the #1 global manufacturer, and the biggest global companies (from Apple and BMW to Dell and Armani) rely on it for their production. That takes a lot of trust, not "fraud and deceit".
Sure there's "fraud and deceit" from small-timers, but then again the US cities also used to be full of small time crooks and hustlers in the better part of the 20th century, as people were getting out of poverty. In the case of China it's internal, not foreign immigrants, but the dynamics are the same.

Well, the same argument could be said for the hegemony of the USA. Why would it extend to the "indefinite future" (especially since trends show the opposite)?
