There’s a short sci-fi story with a premise somewhat similar to Idiocracy. The entire world is populated by stupid people, apart from a small clique of intelligent rulers whose main job is to clean up the mess caused by the hoi polloi. The opening scene is a newsreader reporting on a maritime disaster: a rescue ship is sent out to pick up the survivors, but someone forgets to shut the doors (or something) and the crew of the rescue ship are all drowned as well.
Anyone recognise that description? I’m annoyed that I can’t remember the title/author.
