Utopian Living Standards (unemployed pops generate science/unity) with busted pop growth from the bio route. I'm sure you could find specific civics that synergize. I can't remember off the top of my head. I do know hive minds have a civic that makes unemployed drones generate extra science. The hard part is always getting enough basic resources to support your unemployed population. I do find that at the end of utopian commie play throughs where I control most everything unemployment is rampant and it's fine because I'm generating so much.
I forgot to mention the caretaker robot civic that lets you collect biologicals and give them their best life, so even though bios technically have jobs, they're effectively unemployed artists. And then you can also play an imperialist marauder that steals pops and resources from other empires and maxes out living conditions for those living within your borders.
