Is that alright with communism? Strive for a classless society except for when we like to do classes anyways? I mean starfleet is kind of military and I don't know much about that in the context of communism. But there's also the separation between the worker class in a starship and then the officers who manage them and who get depicted in most of the TV series. I'm pretty sure that doesn't align well with communism. I'm not sure how many exceptions there are in a communist utopia. But I'd like to see some strong arguments when doing away with some of the core values of an ideology. And I'm not sure if there is a better way to organize a starship than 20 century military hierarchy style.
