That's kinda my point tho, in the west they just go maga or some other cult, while these people from China react even more violently and spontaneously (although you can say that the maga causes more long term damage). I don't think statistically or as a group that they have begun to be a problem, but to nip it in the bud, there might be solutions.
First, people should be taught to take things less for granted. But secondly, to dispose of those already having antisocial tendencies quietly, perhaps a campaign to encourage controlled self deportation? Show them that they can go to 3rd world countries, where their wealth will give them the privileges they're angry they can't have at home.
You don't need (and likely can't) make them into likable human beings, but you just need to carrot and stick them enough so that they don't experience a narcissistic break and go LA concert shooter whenever they feel "infringed".
