> Have you ever been there and met the uniform mass persons?

I was born in Eastern Europe in a society headed in this direction. I observed its transformation after the fall of the Berlin Wall.

You felt the overarching power of the state from as early as the kindergarten. Signs of individuality were suppressed and all children were supposed to do things "the right way". When such an institution decided that a child "systematically misbehaves", it was able to take the child away from its parents in another orphanage-like institution that was supposed to teach them good socialist manners. Eventually some of them would end up seriously harassed, physically-ill and sent to an anonymous grave in the backyard of that institution.

I grew up in the USSR, and in the kindergarten, our teacher actually tried to convince us that the correct 5 year old kid's answer to the question, "which person do you love the most?" ought to be Lenin, and not e.g. "mom".

That said, in practice, the quality of indoctrination was extremely variable for the same reason why it was variable for everything else - most people weren't really buying into it themselves, and so even if they were in a position where they were expected to indoctrinate, they did the bare minimum that was demanded of them, which usually wasn't very convincing. I didn't get to witness it as an adult, but according to my mother, by the time you were old enough for Komsomol, very few still had their rose-tinted glasses on.
