The message is good just missed an opportunity to carry over the energy into action. I'll try: since we can't change society so easily, perhaps change the environment as a microcosm? Talk to friends about it. Talk to family. Coworkers. Try intentional things like no-phone dinners. Heads down time. Maybe these things are just as silly. And it's especially hard to alter kids behavior because it's very hard to control external social influences.
If you want to talk about kids specifically, then you'd need some way to alter the anxieties that affect them the most. Anecdotally, it seems like kids (teens especially) end up with lots of FOMO and loneliness. The only structural reforms I've seen suggested as solutions to those were much more drastic than the ones proposed for adults, like preventing teenagers from using social media at all.
Are there really so many employers requiring employees to be permanently on-call? I would only consider working in such an environment if they would be paying enough to retire in a few years.
As for how common it is? dunno, but there was a very funny (sad?) music video that hints that this is fairly widespread phenomena, for young office workers. Quarter Life Poetry, “Circle Back”. One of the final scenes is the narrator being unable to get away from the grind even at home.

You can put your phone on a shelf and if somebody calls you, you can pick it up, or call them back later.
A single person can't change a society, but a single person can talk to 1-2 dozen people and maybe get 1-2 more people to talk to 1-2 dozen more.
