In a world where baby boomers (I forgot the politically neutral term, sorry) emotionally neglected their children, most turned to various media such as tv and internet (or other media) for their emotional management expectations, and role models.
My sister has 3 kids under 10. Every day they watch at least 3 movies, some of them atleast presentable as childlike learning, the others are just "whatever Netflix puts on"
I would argue the most damage has come from the near complete and utter erosion of social communities. As the saying goes, "It takes a village [community] to raise a child." I can't name a role model in my community. In fact, I have no community that I can access without the Internet.
We went from "Survive together; thrive together" to "every man for himself" way too rapidly.
