I'm pretty sure that this has been mentioned in one way or another, but I guess I'll weigh in with my .02. Basically, I do agree that the idea of stupidity is promoted, but the way it's promoted has little to do with any conspiracy theories or anything of that sort. Rather, as in most things in life, nature tends to follow the path of least resistance. Therefore, the default setting is the one that's chosen by the majority - the lowest common denominator. For most people, it is easier to be less smart. (Here, of course, I mean the "true" smart - as in educated and well read individual, not just the loud-mouth one who uses big words). Real education and real brains are hard to build, hence most simply avoid it. Now, would you expect these people to glorify those who chose the hard route? Of course not, they would praise the fool for this is where they feel at home the most. In that light, the promotion of stupidity is not all that strange - it's the default of the nature itself. All we need is just enough brains to survive; that's all that nature and evolution cares about. The rest is up to us, and spending more effort and energy is not worth it for most, especially in a society like ours (American) where we already feel we've achieved more than the rest of the world. The motivation to go further and do more and be smarter is not there, and so the average is glorified.
