Reminds me of a review (written somewhere in the early 60s, I believe) by some Soviet sci-fi writer of Hamilton's Star Kings (1949) and the Western sci-fi in general; to paraphrase, "it's astonishing that those writers would set their decorations thousands years in the future, with wildly imaginative technological advances and inventions, yet when they come to the social systems, all they can imagine is either the feudal order of the past, or the modern style of capitalism".
