Reading over the whole, multi-part exchange between you and @lexiconical, I think it comes down to you starting from a series of premises that are wrong--and that are, as was noted elsewhere, deeply ideological. You seem to think that any society without money is communist, and all communist societies are totalitarian. If those are true, then sure, North Korea and Star Trek are basically the same.

Neither of those is really true though. In the first case, your inability or refusal to distinguish between the terrestrial, resource-poor communism of North Korea and the nearly-infinite-abundance of Star Trek's space communism is clear from your view that societies with almost nothing are functionally the same as societies with almost anything. This ignores the real human impact: people in North Korea are super unhappy, and under a deeply repressive regime that both regularly deploys coercion on its own citizens and must aggressively bombard them with propaganda to maintain a minimum level of consent. The people in the Star Trek universe, while hardly without problems, do not seem to live under the heel of a repressive regime--with the exception of the officers and crew of a naval vessel, which is, as I'll note again below, neither all of the people of the Star Trek world nor even that unusual, since the peculiar conditions of naval vessels mean that hierarchical, disciplinary systems of command and control are necessary.

In the second case, you seem incapable of imagining that the world of Star Trek is NOT a militaristic, totalitarian dystopia--as evidenced by your total refusal to acknowledge the evidence @lexiconical provided that not all people are in the military, that the state does not literally control all economic activity, that non-monetary value exists outside the systems of rank in Starfleet. You seem to think that the life of people on the Enterprise is literally the ONLY way that people in Star Trek live. And while it's true that the show is about a naval vessel, which does have a military, disciplinary hierarchy, and does assign value based on service and obedience to the state, it's also manifestly true that not everyone in the Star Trek universe is in Starfleet. This is what I meant by there being some superficial similarities, but those similarities being, well, superficial; the economic, political, social, and cultural worlds of North Korea and Star Trek seem to be far more different than they are alike.

Now, you can say that Star Trek is unrealistic--but I don't think anyone will argue that a science fiction story with magical technology that eliminates human want is realistic. The question then is more a matter of the value judgments we place on such a fictional world.

So, in short, I reject your interpretation of Star Trek on both ideological and empirical grounds.
