Kids in school see cameras watching them everywhere except inside the washrooms and changerooms. In the school my partner works at, there are so many cameras, you are on more than one at any given time, and the cafeteria is crazy loaded with them. So surveillance to them is a nothingburger.
Unfortunately it'll be really hard to explain to them as they get older why government surveillance is a bad thing.
At the same time it's not just big brother surveillance. Kids tend to know their cellphone can track them (in fact there have been articles here about kids wanting their parents to be able to track them), but more so they know each one of their peers has a cellphone that can be used to record their own actions.
You don't need big brother when you have an actual brother the could be recording your at any moment. I guess the only thing I can really place it with is how back in the USSR days, us US GenX'ers were always talking about how the KGB gets you because your neighbor turns you in.
In other words: kids these days are both the agents and the victims of a distributed KGB - one that doesn't have a structure, nor does it follow a specific ideology. It's a whirpool of ever changing attitudes, that victimizes participants pretty much at random. Thing you did was fine when you did it last year, but is not seen as fine now, and you - not your friends doing that same thing - will get dragged over coals for it, just because RNG made a post about you go viral.
