> - The "lie-flat" movement massively picks up.

This is a serious symptom that is being swept under the rug. Efforts needs to be put in to better understand the issue and enforce steps to resolve it.

I lack the basic training in trying to understand the issue - sociology, psychology or whatever is the relevant field. But I feel that "lie-flat" is just an acute variant of the general issue - "checking out of reality". The other versions are "staying in echo chambers" and being incapable of even listening to different views. "Getting lost in other worlds" - the gamers that spend whole day in games like Fortnite or always flipping through videos in tik tok.
