Yes but those kids weren't at real risk of having their minds completely subverted by for-profit organizations.
Meanwhile, the majority of parents care deeply and are doing their best at a difficult charge. They instill a grounding in contemporary consensual morals, which is all they have ever been able to do. The idea that they have, en masse, "abdicated a sacred duty" is cheap. I'll stipulate that tablets are bad. I don't agree that morals peaked in some edenic past.
I mean, peak father-son time was sending the boys down the mines with their dads. I'm not convinced that screen time is worse.
I regret the industrial revolution as much as the next crunchy hipster, but finding a nice stick to beat it with is not going to raise the floor. Whatever dogma you fancy, the groups you most want to ram it into will never even hear it. Parents who use tablets as pacifiers so they can smoke meth or watch telly are not going to change because you shout at them about the arts and crafts movement. Neither are parents working two jobs without support networks. If you're right, you're pointlessly right.
