I have close friends from China. The stories they tell me about their childhood during Mao's Cultural Revolution are exactly this. The stories are unbelievable. A female friend told me when growing up in Beijing, a relative overseas bought her some leather shoes (when most people wore cloth shoes). She wore them to kindergarten. Her teacher organized a "struggle session" within the class to criticize her (a five year old) for having bourgeois attitudes.
We are going through a slow-moving version of the same thing.
Funny how a generation later, the Chinese went in the opposite direction.
I agree, and the hatred and resentment that fueled the Chinese cultural revolution is alive and well here at this point in our history. I have zero doubt that if given a green light (or even a yellow light) there are literally 100s of thousands or even millions in the US that would have no problem running through the neighborhoods of those more affluent than them, destroying property, looting/stealing, and even killing those they've been brought up to believe are permissible to hate.
