Someone else pointed this out before in a different thread but why should they want to change if life is improving without them? If you look at the US as an example of democracy then at the moment it doesn't make a lot of sense. That being said things are always changing and who knows what will happen in the next 20 years.
If things stop improving for most people in China then there will probably be social unrest and they may move to another form of government or the reverse could happen and the US might decide that it wants a nother form of goverment if things don't eventually improve.
