No brain eating zombies. I'm talking about something more akin to the afterlife.
In the world of the dead, what would my motivations be? Assume a spiritual world where regular food is not required, and "material" possessions have little significance. I don't need to earn a paycheck to keep a roof over my head and if I'm not chasing a career, I don't need to climb a social ladder or improve my marketable skills. I certainly don't need to exercise to stay in shape. Sure, I could create art. I could try to better myself mentally. But why? What's the motivation?
Given an entire society of spirits what would day to day life look like? If you think of a movie like Coco, they have the suggestion of a regular society, but why would there be commerce or government? Why would there be buildings? Where do resources come from?
I'd prefer to avoid rationalizing it with something like "they cling to the habits of the living".
UPDATE: To be more specific, in the current world there are ruling "specters" that can provide a stream of "essence" to the spirits of their region. This creates a traditional communist structure, where sustenance is provided and residents can busy themselves with assigned tasks. There is barter for services. There is a notion of "coupling" and there is certain luxuries normally reserved for the specters. For starving peasants having a place in commune may be enough (1984), but if you were a spirit and life/death wasn't an issue, what motivates you to get through the day? The spirit world in general may have a touch of utopia but needs some more depth to be interesting.
