Wholly and completely resent their parents. Growing up in the later 00s/10s, right as stuff like SMS and especially "social group by text message" came along, it absolutely stunted their ability to make friends.
What it did was disconnect them from their distant peers and meant that making friends outside of their immediate school peers was basically impossible. It also landed them an extremely deep rut of depression, causing them to spend their free time for years sinking into alt-right stuff that actively preys on "people sheltered from social media as kids".
Everything in the under-18 space is organized in real time online behind adults backs. Never let anyone tell you otherwise. Kids plot against the adults. The fact of the matter is that social media is the way we engage with so much art, culture, and society that these sorts of schools hurt kids in the long run.
I leave you with the track Turntable Winding Down [0] from the album Public Domain. The intro/outro were stripped when the band re-released the album "legit", but Archive.org has the original because, of course they do.
