"Nightfall" was remarkably prescient in this way; the story follows a civilization surrounded by multiple suns who have never seen the night sky, much less the stars above. A once in a millennia eclipse occurs and madness takes hold of the planet.
Comfortably Divorced from reality, they were not prepared for suddenly having to confront it.
All people are the same, and the further from reality we stray the more the madness will take hold when we finally return. This can be seen most of all when the upper class is tasked with something as simple as creating a fire, even with the help of a lighter and Firestarters.
Here is the crux: humanity WILL return to reality when the resources of the planet have been used up and industry crashes down. We are currently beyond the sustainable limits of the Earth: sooner or later we will collapse.
This is why The Revolution is important: The System must collapse before humanity is so far technologized that we face extinction when reality returns.
