To respond to those points and the freedom to move from place to place, I'd mention that there still is a registration system in existence, and people who move into the cities don't have the right to register there. They're lacking membership in that city. They're basically temporarily in the city; it's not as if people have the freedom to move where they wish.
Certainly in the market system one can choose one's career, whereas in the past it was assigned. That's got to be progress.
But within China, due to the Chinese Communist Party's policies, when they abandoned Marxism and this planning of the economy, they also seem to have abandoned the commitment to social justice. You're seeing China going from what was one of the most egalitarian distributions of wealth when China was poor to being what is, I think, the second most inegalitarian distribution of wealth now that China's rich.
So for the underclass there isn't a lot of good news. What we see in Beijing and Shanghai is not representative.
