This is pretty much the plot of two books. "March of the Morons" and "Hitchhikers Guide to the Galaxy" In "March of the Morons" the stupid people of earth were convinced to go to Venus to a utopia, but they were instead exterminated. The author however is a Jew, with obvious holocaust references. In "Hitchhikers Guide" the stupid people were convinced that the sun was going to blow up and sent in a large spaceship in a random direction. Unfortunately that ship crashes to earth were the survivors become our human ancestors. Both of these works are frequently cited along side the movie Idiocracy.
