I think you hit the nail on the head there.
Boomers for some reason decided it would be preferable to park their kids in front of TVs in lieu of raising them.
And as much as many are eager to pass the blame up another generation, I don’t see that anyone else taught them to do that. It was simply easier and more convenient, and allowed them to pursue things other than being good parents.
And another issue, is that the mistake is being repeated.
