Here in Germany parties actively ran on the promise of raising and fixing the pension levels in an already unsustainable system. Alongside other gifts to certain voter bases. The one left out (I assume partially because they are not able to vote): The youth.

so they were lying, except to the youth, because to them they didn’t have a message. that’s a positive thing to me.

But you are right that they might influence smaller changes.

part of my worries is this, but rather how will this affect all of them, when sociopathic people will start targeting them with even more brainwashing/reeducation content.

To take one of your examples i could see that for something like the smartphone ban. But would that be so bad?

what do you mean? the banning the school-level banning of it? the problem is not smartphones themselves, but what they can do.
playing games and scrolling social media on lessons. taking pictures of your peers against their will, like when they get humiliated. using the infra blaster to fuck with classroom equipment. all of these were happening in my class, just a few years ago. unless your solution is mandating school-issued spyware on every phone, which I don’t support, the only solution is to ban them in one way or another. possibly only on lessons. and then somehow solve the problem of stolen phones, when someone knowingly took away a different phone at the end of lesson.
