This book, written in 1951, obviously inspired Idiocracy. But the story is different. In the story, a group of non-morons get together to preserve human intelligence, to prevent it from dying out. In effect, this group is an island of 1950s sanity surrounded by an ocean of (modern) idiocracy. This is quite optimistic and seems very difficult to do now. Humanity is already too stupid to recognize the impending problem of idiocracy and to do much about it. The only hope is for some non-moronic tribe/religion like Mikraite to preserve human intelligence.
