there's a good classic Sc-fi story by C M Kornbluth called "marching morons" about that sort of thing, and how they solve the population problem with the help of an American huckster unfrozen from the 20th century.
it's interesting because a lot of the catchphrases from that hypothetical future run by idiots are put into the movie "Robocop" without explanation-- an in-joke. That insanely stupid slogan "I'd buy that for a quarter!!" for instance
i believe the reason more Americans act like stupid sluts is a generation of parents refuses to pass on the judgement that stupid sluts are stupid, and slutty.
The core joke of Hitchhiker's Guide to the Galaxy is that of course no civilization would develop personal computers with instant remote database recovery, and then waste this technology to find good drinks.
Steve Jobs has ruined this joke.
