Why do you think that the privileged people miss the obvious truths?
Well, several reasons. For one thing, the more educated you are, the more indoctrinated you are. After all, propaganda is largely directed towards the privileged. For the mass of the population, there is propaganda, but it's mostly to try to get them out of our hair, you know, it is distraction. Get them involved in professional sports, or sex scandals, or anything. Just keep them away from us. That's why the political system in the United States has now degenerated to the point where the only issues that are talked about are what are called "the culture wars."
