The majority of comedy works because there is truth in it. Sure, Idiocracy is prophetic, or we wouldn't be discussing it today. Nobody discusses South Park's "Bigger Longer Uncut" like Idiocracy because it doesn't really engage this kind of truth.

What I cannot tell is if people have always been this moronic and we're only more aware of it because of ubiquitous cell phone camera technology and the Internet's capability to rapidly distribute awareness of dumbness that would have otherwise stayed regionally isolated.
