There was a joke I remember in the episode they bought Rosie, their maid-bot: Jane said she was exhausted by all the cooking and cleaning while simply pressing two buttons that said “cooking” and “cleaning”.
I also enjoy the conspiracy theory that Jetsons and Flintstones exist at the same time, but Jetsons are upper class and live in cities above the nuclear rubble, and mutant, talking, dinosaur adjacent monsters below.
