I'm an American living in the U.S. with a Chinese girlfriend who lives in China (in Chengdu, Sichuan province). I've visited her in China and gotten a pretty good sense of Chinese attitudes, and I can tell you that your stereotypes about what it's like to live in China are nonsense.
Most Chinese are very satisfied. As a practical matter, very few Chinese feel "oppressed" or lacking in freedom. I'd read about the great firewall of China, and it's true that when you try to access Google, you get the Chinese version, which (I'm sure) blocks a lot of content. But I was easily able to access the websites of the Washington Post, the Los Angeles Times, and the New York Times, as well as Wikipedia. I was able to access my American email account. I was able to access and participate in Anandtech forums (until my Chinese IP address got banned by Anandtech - I'm not sure why). All the news and information I sought was available to me. So any Chinese interested in getting the unfiltered news - or who wants to send and receive emails free of censoring - can easily do so.
Of course, if in China you want to be an un-censored journalist or seek to change social/political conditions in China or wish to join a controversial religious or political group, you're eventually going to get into trouble. It's undeniable that America has more freedom of expression and association than China. But for the vast majority of Chinese, they do what they want, when they want to, without any fear that "Big Brother" is watching them.
On a per-capita basis, China is much, much poorer than the U.S. The standard of living is lower. But people growing up in that sort of environment don't experience a sense of deprivation, since those around them are in the same situation. Thus, I didn't run into any Chinese who were thought their lives were shitty and looked to the U.S. as a sanctuary.
Edit: Oh, and that statement in the article that a rich Chinese like Mr. Su cannot have a second child because that runs afoul of the "one child" law is nonsense. It's is widely known that anyone who wants to have a second child can pay a bribe to the authorities. At Chendu and Beijing airports, I saw many families with two children, and when I asked my girlfriend about it, she explained the realities of the one-child policy.
