So you were really going to tell someone they're cherrypicking and quoting a survey that said only 11% of people were "very satisfied" and just hope no one looked through your wall of text, huh?
China just went through a period where in a single generation they eliminated more poverty than any other country in history (save the USSR). Why is it so hard for you to believe that children born subsistence farmers would have a positive view of their government when they're middle classed and middle aged?
