Post-apocalyptic religion in fiction.
A common trope in the post-apocalyptic genre is that aspects of liberal capitalism get enshrined as religions. There’s a sect of people who worship the Almighty Dollar, use malls as temples, and believe that the cataclysm happened because people didn’t perform the ritual of shopping enough.
This is often meant to be a satire of the way things are. Taking capitalist culture to its logical conclusion, a less subtle idolization of Capital. It often comes off more as just another form of capitalist realism, as Fisher would say. Imagining the end of the world before the end of consumerism.
The things that are cherished today wouldn’t necessarily be cherished in the aftermath. Even in the darkness following the superpowers of the Bronze Age people didn’t enshrine their unsustainable bureaucracy and proto-globalization. They enshrined the warrior spirit that made those powers dominant.
The very same spirit which created the comfort that eventually made them vulnerable to decay. The same spirit which was held in some form by the Sea people who struck the final blow. Consumerism as well as liberalism and capitalism altogether would be held in even greater disdain among their ruins.
