Earth is struggling from the ravages of nuclear Death. The leader of the first expedition to Thistledown, an asteroid starship, Garry Lanier, has grown old, bitter, weary, unwilling to live. Suddenly he reunites with General Pavel Mirsky--who cannot possibly exist because Mirsky disappeared with the Way, an endless corrider slicing across space through universes.

Eon/Eternity (both by Greg Bear)
But many people survive, and a society quickly develops post-war. But it is dominated not by those who were most individually prepared, but by those who contributed the most to their neighbors and communities.
There is some overlap of course; some preppers have a lot to give and do so. But the ones who isolate in compounds with their hoard for too long emerge into the new society to be met with scorn, or even outright violence in some cases.
I had not thought about it that way but it kind of makes sense. It’s easy to like someone who is helping you. And shared hardship can bond a group of people.
It’s a great book, in addition to this aspect (which is a somewhat minor part of it).
