In the film Full Metal Jacket, the character Pvt. Pyle, who is the most child-like of the new recruits, goes mad, after being treated as inferior by the rest of the recruits and Sergeant Hartman. At the beginning of military indoctrination, Pvt. Pyle is physically unfit and a friendly guy, but at the completion he is physically ready to go but mentally unfit. The other recruits say he may be a "Section 8," meaning he is unfit for military duty. But who is the real crazy one? The one who kills himself or the one who kills others? Pvt. Pyle couldn't take the humiliation, the indoctrination, and the dehumanization. Before he blows himself up, he says " I am... in a world... of shit!"
Similarly, in a society largely organized by military influences, such as America's, those who resist the fascist media's indoctrination are viewed as chicken-shit maggots who can't take the tyranny. In other words, if you resist you are insane. That kind of explains all the pills and drugs in American society. I know there is more to it, but the growth of the medical psychiatrists is in line with the larger purpose in American society. If you are not fully indoctrinated then you must be crazy. Ron Paul was called crazy during the presidential election, and so is every other truth seeker.
And who are the recruits who first raise the rumor that Pvt. Pyle may be going Section 8? None other than Pvt. Joker(Obama), and Pvt. Cowboy(Bush). Gotta love Kubrick.
