“what evidence do you have the Chinese people want to be free of the communist government?”
The Hong Kong protests? Tiananmen Square? The demonstrations that erupt routinely across China? All the political dissidents in prison and being executed? The mass Gulags they require for the Uighurs? The Tibetans? Falun Gong? Christians?
But really, it is human nature to want to be free of oppression.
In a natural setting, yes, but most Chinese live in high density artificial hives. While China's land size and middle class population are comparable to the USA, they also have 1 billion lower class people that envy and hate their neighbors in 3 dimensions. If China held a free election tomorrow to replace the CCP, the new boss would be the same as the old: socialist and authoritarian.
