The Culture novels by Iain M. Banks are the best working out I've seen of the concept of post-scarcity. There are ten, IIRC; I did a reread this past couple years and am two from the end.[
Tell me..as a speculation..what happens to the Capitalistic model in a post-scarcity world? What happens to the Social Democratic model in the same world?
If you didn't have to work..unless you wanted to..what would you do? Can Technology give us post-scarcity? Would our true leaders allow it?
