This comment at the New York Times about China I think is interesting.

China's communist regime will collapse in the next 20 years. Probably sooner. Its economic model is totally unsustainable and, having given hundreds of millions of people a taste of middle-class living, the next big economic shock will result in revolution.

A generation of people has become accustomed to ever-increasing growth and modern luxuries. If Xi thinks all those people will be happy to let their standard of living slip backward for the good of the State, he is in for a rude awakening. I don't care how many tanks and soldiers you have, when a billion people pick up pitchforks and storm the castle walls there ain't nothing going to stop them.

The amount of financial fraud and corruption in China is breathtaking. I investigated corporate fraud and crime at an international law firm for many years, and I have been to China more than 50 times. The whole economy there is a house of cards. I have no doubt the real economic growth was never as high as they claimed, and the real economic risks are much higher than they're now claiming. You simply cannot trust any numbers put out by the government there. So you can bet that the problems are much worse than anyone realizes.

Eventually all that bad debt and financial fraud will come home to roost.
