Yes, we've had vertical cities with economic class strata, but have we had frigid vertical cities with economic class strata? This is an incredible innovation in the dystopian novel genre.
N = 2 (this and judge dredd) right now, but was there a rise in fiction in the 70's/80's where they did the 'people live their whole lives in a skyscraper and didn't come out' thing? Is there some underlying societal fear I'm not super aware of? Or am I making too much of two examples?
It was (is) a real thing that archtitects have thought about. In 1969, the concept was named arcology. I learned about them through SimCity 2000 which helped popularize the concept.
I think, culturally, it's an offshoot of Modernist thought. One trend in modernism is that science can be used to find more efficient ways to live, and that science will lead to human dominion over all natural processes. Some thinkers took this to one (terrible) conclusion and wondered about if people could live, work, and socialize all within one building; one efficient and contained (and human controlled) space.
Real skyscrapers were often designed with this in mind, and we still see the echoes of it today with concepts for Mars colonies and hanging-building mega-cities in Tokyo.
Yes I know about archologies, but those are all just concept ideas, which is interesting that it lead to these dystopian ideas. I was wondering if there was more to it than just that.
The building also incorporates shops including an architectural bookshop, a rooftop gallery, educational facilities, a hotel that is open to the public, and a restaurant, "Le Ventre de l'Architecte" ("The Belly of the Architect").
It was a huge trend after the war for a variety of economic and ideological reasons.
I recall reading quite a few of those, but don't recall any specific building ones, esp not which much themes of 'people stop interacting with the outside world'.
The Caves of Steel was basically named for it, with a major plot point revolving around the fact that everyone is too agoraphobic to have committed the murder because of generations spent living in giant domed cities kept isolated from the natural world.
