Not everyone is an American, and that's fine. Asians--on average--just care more that things "just work" than having more freedom to faff around. It's like Apple users versus Linux users. The Chinese government is a good government for the things that most Chinese people actually care about: economic development, building infrastructure, keeping trains running, etc. At the end of the day, most Chinese people in Hong Kong aren't missing the political freedoms that Americans would miss in their shoes, and value the things they do have that the government is good at.
