Most of the population won't have any use for it - they'll have no reason to question what's in the mainstream.Exactly. The point of information control in closed society is not to avoid the exposure of particular events, but to suppress entire lines of thought.
F.ex. How would you begin a conversation with a North Korean about democracy?
Their very concept of the idea, inasmuch as they are likely aware of it at all, is alien to your concept.
Which means that conversation has to start all the way underneath, at the underpinnings and philosophical bases of democracy. Which is a much more difficult and lengthy conversation.
Which is the entire point, because most people won't make the effort. Anymore so than the average American is capable of and interested in learning enough to have a nuanced conversation on the differences between Soviet and Chinese communism.
