It's an exceedingly common theme in sci-fi, but particularly the space opera genre. In any literary universe where humans occupy multiple planets, at least one of those planets is an agrarian society who has renounced all the higher technology that brought them there.
Peter F. Hamilton loves talking about this. Offhand, I can't think of a single one of his books that doesn't at least mention this concept. He really likes to explore the very long-term evolution of the relationship between humans and technology. You get simple low-tech societies governed and protected by the most sophisticated AI it's possible or conceivable to build, lots of backwater planets with no money for technology, idealistic societies that set up a new way of life, farm planets, all sorts.
Look at 'The Dreaming Void' trilogy. It's very explicitly a juxtaposition between high 30th century intergalactic technology and a society living on a planet where electricity simply doesn't work. It's one of my favorites.
