Assuming the gender gap is real ... , China is facing a sizable and growing population of young men who have no prospect of marrying and settling down, a situation conducive to crime and political unrest—which, as far as the Chinese government is concerned, are one and the same. In August China Daily quoted Chinese officials and academics who blamed “an increasing crime rate, growing demand for pornography, and illegal [forced] marriage” on the disproportionate number of young, single men."Thank Deng Xiaoping for Little Girls," Reason, December 07.
If this dynamic takes the same form as that found in the Middle East---a disproportionate number of young single men frustrated by the prospect of always being single and frustrated, in this world at least---China will be only too happy to export that unrest rather than deal with it domestically; in fact the unrest will export itself. We have enough of that 8@7sh17 already in the Arabic 72-virgins flavor.
Ordinarily, I'd take reassurance from Thomas P M Barnett about the relative threat posed by China compared to other US national security threats. The generational aspect shown here, though, makes me reconsider.
