Idiocracy is an absurd comedy that triggered some people's prejudices and made them think they were right. (It doesn't look like the author shares those prejudices. That's a nightmare scenario, you make some dadist art and an entire population of bigoted people make you their leader.)
Don't look up is a comedy about global warming.
Idiocracy is based on a false premise
I'd love to learn more about this. I thought it was based on The Marching Morons by Kornbluth and the subsequent discussion between Niven and Asimov I read many years ago. It seemed true then. It seems more true today.
OK, fiction writers aren't (often) scientists so while such discussions might be interesting you should not take them as authoritative & evidence based.
It's a slightly eugenic fallacy which assumes that a) poor people are poor because they're stupid and feckless, and no other reason like the inbuilt injustices on our society (it's considerably easier to stay rich than to get rich) and b) education, upbringing and innate intelligence are the same thing. Life situation isn't genetics.
