I’ll counter that with the caveat that my kids are grade 5 and younger. We’re very involved in school and other activities - my wife is a PTO president and long time member, I coach youth sports and other community type programs.
The kids we have seen mostly don’t engage with social media directly. But the ones who transition from cute 5-6 year olds to problematic 10-12 year olds have a key common factor. Tablets. You see kids as young as 2-3 hiding under a table engaged in some awful kiddie YouTube trash or a game. It ends up being a pacifier that induces anxiety, and I think that effect combined with social media is powerful and difficult for kids to manage.
In terms of targeting, i actually think that things are better today. Through lawsuits and reporting, I learned that my childhood Boy Scout Troop and church was infested with pedophiles. The Boy Scout leader basically roamed the country and landed in NYC where he was eventually arrested for an unrelated rape. Today, there’s extensive background checking everywhere and it’s more difficult for a known offender to be in that position of trust.
Sports and the college recruitment funnel are another thing hurting kids. I had a kid drop out of little league because his soccer academy coach flipped out that he, as a 10 year old, isn’t fully committed to soccer. So he’s playing “elite” soccer, at a cost of almost $4k, because that’s how you make the high school team.
