I recently saw a meme with a girl's face saying "Slams socialism because there's no such thing as a free lunch... Doesn't realize the line comes from a novel about socialist revolution." This is a reference to the Robert Heinlein novel The Moon is a Harsh Mistress. The phrase is used heavily there, but the novel is definitely not the origin of the phrase, so part of the meme is definitely wrong. I was more surprised by the notion that the revolution in the novel was considered socialist, as I had always read the novel as a libertarian fairly tale; a thought experience on what an ideal minarchy or anarcho-capitalist state would look like, which in my mind is the exact opposite of socialism in any form.

Is there evidence that the revolution in the novel has socialist ends (control of the means of production, redistribution of resources according to an ethical criteria, regulation of business cycle ect)?
