A number of countries have experienced revolutions at one point or another, and all petered out because they were experiencing one-time economic gain from exploitation of untapped resources.
i think of china now as russia was circa 1918--after a couple fantastically successful five year plans, Stalin wrote _dizzy with success_, which explained that the USSR was going to overtake the rest of the world because of its rapid economic growth. This growth was mobilizing untapped resources and getting more people to work, largely because of central planning. China is still progressing because of the cultural revolution (not so much its evil, evil, evil side effects) and this probably will not last:
first, they're also mobilizing their population almost like britain was circa 1800s industrial revolution. pretty soon there will come a time when the population doesn't have the money to buy the goods that are being produced, and nobody's gonna pay their workers enough to buy the stuff that's being produced, and the overseas markets will become more-or-less saturated as well. If the workers expect to be paid more, they'll have to unionize, and let's take the very unlikely possibility that the gub-ment allows this, they'll start cutting into the growth with this (though in theory they could make it much more sustainable).
second, the chinese economy and the government are so interrelated that it's quite a bit problematic because there are any numbers of problems with corruption, which can really screw foreign investment. the government doesn't know what it's doing, other than being vaguely hostile to just about everybody and encouraging foreign money and free trade (for everybody but themselves). If the government remains hostile, it's only a matter of time (china's GDP has to double) before the US sees them as a rival and all of the sudden their economic well-being tanks.
I personally think that individual freedoms are absolutely necessary for continued economic growth, and that as long as china is an oppressive totalitarian regime that threatens to invade taiwan and ranks in the five worst countries re: freedom of the press, their growth will be hollow. If you want to read something interesting about this, look at PJ O'rourke's book _eat the rich_, which has a chapter on shanghai and he surmises that the chinese are "growing" because they're building crap, but they're building crap nobody really uses, and there's still an immense immense group of people who're sucking it up.
anyway this is just the ramblings of an idiot; i'm interested to hear if anybody thinks it has any merit.
