I used to think that as more Chinese people entered the middle class, they would demand more political rights. It's generally the bourgeoisie that does this -- they aren't poor anymore and they want respect, they resent being looked down on and the monopoly on political power held by the entrenched aristocracy (which in China would be the powerful families in the party), and so on. But that hasn't happened as far as I can tell. Maybe it's because the people in a position to successfully demand political reform aren't staying in China.
