That's the setting for The Electric Church, by Jeff Somers. There's a very small capital class who own all the automated manufacturing plants, etc., and they live in obscene grandeur. Then there's the rest of the world which is basically a slum, brutally oppressed by the police force to keep them from rising up. The population gets everything they need to survive, but it's all fairly shitty - the technology for a post scarcity society exists in the setting, it's just hoarded by the most obscenely wealthy.

Pretty decent sci-fi, just pretend he didn't write any sequels tho.
