The best way to deal with teenagers, is if you are cool in their eyes, then they will naturally try to copy you. This is hard for most parents, try too hard to be cool and you will be relentlessly mocked. In fact if you can’t be cool, it’s best to just be neutral and let them drift the way they drift, because if you try to impose too much, you just encourage their natural rebellious streak and get opposite results.
The Chinese government has always been in the position of the uncool parent who is trying to take control by being a disciplinarian. Thinking they can control US public through some hidden levers, is like thinking the parent secretly is making the teenager do his bidding by playing 5D chess. It is a fantasy. The US regime was more cool, maybe not as cool as actual Gen Z, but cool enough that they were not relentlessly mocked. Unfortunately this act, just exposes them as uncool after all, and makes them get relentlessly mocked. If the goal, is to win hearts and minds, US could not have scored a better own goal. That said, maybe this was going to happen anyway, the newer generation seems the most ironic and the quickest to mock existing social mores and ideals, and this act just sped up the process.
