Trek isn't even communist. Picard retires to his family estate (and never leaves, ever, infact nothing happens after that), Quark owns his own bar, multiple dozens of episodes revolve around determining who owns bits of property. It's just post-scarcity.

The twist is that Picard, Quark, et al are actually corrupt government officials who enjoy the scant fruits of the communist system, while the rest starve off-screen.
