Many people like to say "Idiocracy is a documentary" or some similar thing implying they think it's realistic. I've never seen anybody take the premise of the movie seriously though. If idiots are reproducing out of control and that will lead to a bad result, doesn't that mean we should reduce the reproduction of idiots and increase the reproduction of the intelligent? To avert Idiocracy we need eugenics, no?
We can probably make a lot of progress investing in schools, making higher education more accessible, finding more engaging teaching strategies, ensuring that parents have all the resources they need to care for their children...more access to mental health services...
