Or, if that doesn't work (because the robots are too dumb), you can at least split off the economy into a "poor" and a "rich" part that are mostly disconnected from each other.
What if the 99% of 'poor', create their own economy, own currency, start opening shops, small factories, etc...
Could we have an entire society without the rich? Reboot an an actual economy based on real goods?
Including the security roles that ensure the unemployed workers don't forcefully express their dismay at being redundant.
I think it's very possible some of these folks have convinced themselves otherwise, and have largely eliminated the folks who'd say "you fucking idiot, no" from their lives over the decades.
