Chinese have revolution running through their veins. This trait is similar to the French taking to the streets in protest, or Americans writing letters to the editor or going on talk-shows to express their discontent.
Revolution has been engrained in Chinese culture for centuries. The trouble-making Monkey is portrayed as a hero and depicted in cartoons. Children learn that trouble can create clarity, and it is not mischievous to be a revolutionary, if you strongly believe in something.
Because this revolutionary characteristic in Chinese citizens is encouraged, it is very likely that another uprising similar to the Cultural Revolution could happen again in present day
China.
Most of the ingredients are already present. There is extreme economic inequality.
Combine that with the culture that encourages revolution, the only missing piece is someone in power to champion the cause and spark the conflict.
Mao played that role in the Cultural Revolution, and without his support, the Red Guards who were once squelched by the administrators, would not have been able to rise up and revolt successfully.
It is this last ingredient that holds the key to a successful revolution.
If cooperation at the top is not present, an attempt at a revolution could end up as another
Tiananmen Square tragedy (June Fourth Incident - 1989).
