Not much of a revelation, just an observation, but how much of sci-fi pushes the ideal that Humanity's path forward is unification?
Star Trek is a major one, and many would state it was a progressive show, and it earnestly was.
It also stated that in its ideal future, there's a Federation of like-minded extraterrestrials, and as a member species, Humanity lives in a united, post-scarcity society under a single government.
To that end, how many alien species in these stories are so inhuman, in that they have no differences, a world-wide government, a single language?
It's laughable how direct the propaganda was, and continues to be.
Just checkout Cyberpunk as a genre from the beginning, cool as shit genre but the politics are ALWAYS pro socialist or commie or at the very least anti capitalist.
TBF, I don't think you're going to find anyone who writes about evil megacorps in fiction yet still extols the virtues of capitalism within that same work.
Obviously, it's cronyism leading to corporations adopting a de facto government model that would be to blame, but people's heads don't fire on all cylinders when they're passionate about their feelings.
Right now we have socialists and communists actively cheering massive global corporations as they circumvent our rights in order to enforce leftist tyranny from the safety of the "free market". It's fucking weird.
