They did complain a lot about how the CCP plunged the country into the largest famine in history because of their incompetence. It was this incompetence that led to the rise of Deng Xiaoping. Mao then launched the Cultural Revolution during which different factions in the CCP fought with each other rather than "keep their head down". At Tiananmen Square in 1976 millions of people, peasants and rich, shouted slogans attacking Mao and the Gang of Four. Deng Xiaoping then launched the economic miracle by reducing CCP involvement in the economy .
To say that the history of modern China is a long, stable period where the people never spoke up and built a powerhouse economy by listening to the directives of the all knowing CCP is historical revisionism at best.
What about TW? I'm not seeing the connection to the PRC there.
Money wouldn't have flown into PRC (and it would have collapsed with the rest of the communism) if the US hadn't opened up investment.
