Global Class War?

It looks like the Chinese economy goes down as well as up. This, to me, is what's often puzzling about the "globalization" debate, but also national security debates about China -- in both instances it seems to be regarded as unproblematic to assume that China will indefinitely maintain an 8 percent annual growth rate year after year and what we need to primarily worry about is how to respond to this miraculous turn of events. It makes much more sense, it seems to me, to worry about how to cope with serious Chinese economic problems.
