In TNG, Picard says that the Federation has evolved past a need for money. Indeed, we never see any.
In DS9 though, Quark talks a lot about bar tabs and costs. Surely O’Brien and Bashir don’t get free drinks, so how do they pay? I’d assume that any Ferengi worth his lobes won’t accept anything that can be replicated, so do Federation officers get a stipend of tradeable “value” when interacting with cultures that still expect payment?
I think there’s also a reference to Quark paying rent to Sisko for running the bar. Presumably that’s denominated in latinum. I wonder where it goes? Maybe the secret “Garak black ops” fund.
Is bolarus federation? I’m not great at knowing which planets are and aren’t. The federation credits beverly uses at far point could still be in line with my labor voucher theory, but I think you’re right about it being earth, not the federation, that’s entirely post monetary. Now that you mention that, I’ve seen episodes where they say you have to be a unified planet to join the federation, no caste system, etc. But never have they mentioned on screen you have to be post monetary. Also, as up thread it was mentioned, quark is paying rent on a bajoran station, so probably bajor has money, and they were all set to join on a few occasions, so yeah. You’re right. The moneyless folks are Earthicans, not federation members.
@DharmaCurious There is a DS9 episode where Lwaxana and a Bolian do what seems like parliamentary oversight. So I suppose they are.
