I used to think that as the economy developed and as you got a rising middle class who owned property, they would want to have the right to participate in political decisions affecting their property. This is a normal political science idea. But what you're seeing in China, it seems to me, is nothing like this. The middle class appears to have been co-opted by the power and business, the Chinese Community Party, and maybe they realize that if there was effective democratic change in China and the vast majority of the population were empowered with democratic rights of citizenship and a notice of entitlement to rights, this would affect their privileged position.
So it seems the situation in China is quite stable, but there are a lot of people underneath who are feeling unhappy and not seeing the benefits of the amazing economic transformation reaching them in a meaningful way. As those people gradually become more enriched, I expect they will become more and more dissatisfied with the existing political arrangements, and one could see people's movements forming. But I don't see any indication of this in any foreseeable future, frankly, I'm sorry to say.
