Consider Hanna-Barbera.
In The Jetsons all the houses are built atop impossibly tall poles, like off-brand Space Needles. Their residents can engage in FTL jaunts in personalized flying saucers anytime they want. The Jetsons have a robot maid.
Yet George Jetson also has a reassuringly mundane job doing some kind of management with Spacely Sprockets, a company that makes―you guessed it―sprockets. Just as Fred Flintstone was a construction worker who happened to use dinosaurs and mastodons as equipment. What Hanna-Barbera was doing, in essence, was to take a very mid-20th-century kind of prosperity and project it as far into both the future and the past as it could plausibly go.
Of course from the point of view of the actual (to them) future this seems very quaint. Many markers of the 20th century economy―things like department stores and trains full of business computers―have disappeared with nothing much to replace them. The future has been depopulated of its onetime dreams.
