You should read “Harrison Bergeron”—short story by Kurt Vonnegut. It deals with a future where everyone is reduced to the lowest common demonominator in the name of equality.
I will....I saw a movie (that was supposed to be funny, but wasn’t) where a guy from the present lay frozen for a generation and when he’s thawed out he finds that in the future everyone is stupid, lazy and useless. He winds up being king, or something because he’s the smartest guy there. It was supposed to make me laugh but frankly I didn’t find it far enough from the realm of possibility to be amused!
