No doubt China is changing and perhaps a burgeoning middle-class will exert different political pressures.

However I view the metric of "produce more than consume" from a proxy lens. That is, it serves as proxy to see the net-sum health of "China Inc". As long as that metric is positive, then it indicates that the net economic forces still favor the structure that got them here.

Obviously anythings possible, and highly dynamic revolutions can spring out of nowhere.
