All citizens of the People’s Republic of China who have reached the age of 18 have the right to vote and stand for election, regardless of ethnic background, race, sex, occupation, religious belief, education level, property status or length of residence. The caveat is most candidates will be members of the Communist Party although there are candidates from other local or reginal parties and some are elected. However, the constitution insures the Communist Party will always control the National People's Congress.
Satisfaction with China’s government has grown stronger and stronger over the years. 40 years ago, most Chinese could hardly afford a a bicycle and all travel was restricted. Today they are driving cars, 297 million of them all over the country. There are more cars on the road in China than any other country including the US. China is the number one car market in the world. Just as economic success has come to China so has personal freedoms certainly not what we enjoy as Americans but far greater than they were 40 years ago. The Chinese can change jobs, move across country and afforded a great deal personal freedom with little inference from the government. The one thing you can not do in China is openly attack the government. Had the attack on the Capitol occurred in China, those that survived the attack would be serving long prison terms today. Surprisingly, China's crime rates for violate crime is almost equal to the US inspite of their tough treatment of criminals.
Capitalism is not only tolerated in China but encouraged. There are less government restriction on businesses in China than in the US. In fact the government is often criticize for the lack safety restrictions, violation of workman compensation regulations, and general treatment of employees. As long as businesses keeps their noise out government business, the government will do likewise for them.
