All that I would add to FCD's comments is that, like all societies, any collapse in China will be at least mildly surprising. Things always seem to creak along until the bottom suddenly falls out. Why should Russia have collapsed in 1917 and not decades earlier ? Why did France hold at Verdun only to collapse 24 years later in a situation with far fewer casualties ?
China is a communist holdout. Their system has mutated in an attempt to survive, but the effort is a band-aid. At some point, the band-aid will be ripped off the social wound.
