You can copy the whole of Gordon Chang's book predicting China collapse and paste it here, if you can be bothered?
Alternatively, you can pick over Michael Pettis' papers and forecast an economic collapse in China, followed by colour/flower revolutions.
There is no denying the problems and huge challenges, but which big nation hasn't got huge problems?
Still, China will not collapse, not in your life time anyway.
You can wait for China to collapse, and I will wait for the USD collapse, and gold price in the many thousands in USD, and my gold stocks shooting to the Mars/Moon.
