I want to shift gears radically, and I want to look at China. What you have said about China was utterly fascinating to me. In particular, your emphasis on the inevitability of corruption.

Some of the stories you tell are extraordinary, unbelievable,. And why you suggest there's a tension in the system between too much corruption and the inevitable of the hostile going on.
