Idiocracy. Great movie, it shows the decline of society due to the lack of education and increased birthrates of those who could not care less about anything but corporations. In one scene they go to Costco and the greeter says, “Welcome to Costco, I love you.”
The person who replied to my original post thought the movie promoted eugenics. I guess to a point, but it is more of a warning than a glorification.
There used to be a saying on early image boards that have helped me more times than I can remember. “Lurk moar”, it has served me well. Even getting used to office culture. It helps to not make any faux pas that would make it harder to get along.
