Wait, wait, didn't we already read this scenario?

So the planet kicks its undesirables off onto its Moon. The undesirables can't come back or don't want to. They develop a fairly simple society without laws and maintain it and learn to realize that they've come to terms with a harsh environment and created something rather cooler than Earth, where pestilence and overcrowding and, most of all, the waste of resources and land has come to reign. So, is this The Dispossessed or what? Or The Moon is a Harsh Mistress?

Our descriptions of utopias apply here. The Earth of Heinlein's novel is not poor and is not overcrowded, but just the result of poor planning, says the Prof, and God knows I trust the Prof. It's parasitic and violent and unclean. Luna, though, is sterile, well-managed once authority is broken down, and has straight forward, easily understood customs. Are they all set morally? Seems like it to me, I don't see much evidence of guilt among the Loonies. And, like the Annaresti, is it possible that a lush environment would ruin their systems? Prof states that their systems exist according to their environment, such as line marriage being most effective. If placed in another environment, the society would obviously change, but would it retain the qualities that harsh life instilled in them?

That the Annaresti came by their unique and environmentally effective approach to socialism through striving for it sets them apart from the way the varied people of Luna adapted to their environment and dropped old customs. But the similarities in the end are downright entertaining. Especially so is the way that they each still interpret conflict differently. They each have fairly complete understandings of human behavior and how to discipline it, but God knows they'd never get along.
