We are exerting control, but not complete control, and it's certainly not fascism. Ideally, yes, everyone could understand every concept from the ground up and be able to engage in reasonable discourse about anything. At this point, the complexity of the world precludes the majority of people from doing that, which is why we have specialization. Practically speaking, people rely on authoritative sources to gain information about something so they can form opinions and make decisions. Those authorities do define what's reasonable based on different attributes, and in doing so exert control, but that doesn't make what they're doing fascist. It's done because the amount of complexity present in the world requires it.
