Economic collapse? Are you insane? China very likely has a property crash in its near future but even the very most developed parts of China are not near to Korea, Japan or Taiwan. There's a lot of room for China to grow and there's no reason to believe growth is under 5%. Maybe heavily state directed capitalism can't reach South Korean levels of prosperity but if all of China reaches Shanghai prosperity that will be success.

And the Arab Spring was in very large part a result of rising bread prices as well as being a massive failure in every way outside Tunisia.

Unofficial indicators of Chinese GDP often suggest that Beijing’s growth figures are exaggerated. This column uses nighttime light as a proxy to estimate Chinese GDP growth. Since 2012, the authors’ estimate is never appreciably lower, and is in many years higher, than the GDP growth rate reported in the official statistics. While not ruling out the risk of future turmoil, the analysis presents few immediate indications that Chinese growth is being systematically overestimated.
