Just a thought.....anyone ever seen the movie "Idiocracy"? It's not a bad movie, kinda funny, but not great.
The basic premise is this.....500 years into the future the human race is dumb as all hell. Basically the uneducated trailer trash gene pool tends to reproduce more than that of those of higher education. Eventually intelligence and higher learning are a thing of the past.
It's kinda opposite of the Darwin awards but a kind of scary example of how the dumb ones can outproduce the smart ones.
