Maybe. Do you forget that people use to not have phones or social media and they still had independent thought? Just because kids aren’t introduced to videos and comments about politics at a young age, doesn’t mean they’re going to be brainwashed by the ruling government. Societies operated just the same before social media.
Edit: Dont get me wrong, there could be ulterior motives, but kids will have other ways to educate themselves on the happenings of the world beside social media
