I have always been a fan of Star Trek, particularly Star Trek: The Next Generation (TNG).
A society where money does not exist, where people work to better their skills and themselves, and function outranks position.
I don't see them filling any forms, or having problems getting food. You can get anything you want, but aside from reginald Barclay, no one is addicted to the holodeck.
A world where people can turn down omnipotence and other God-like powers just to enjoy being themselves.
A much more enticing existence than, say, the one in Brave New World, where the entire society is enslaved by drugs administered by the administration. Or the fanatically religious Dune planets. Or the dirty, very '70s Star Wars universe.
Star Trek displays a socialist utopia. Hey, no money, right? As well as some forms of anarchy, within a military outfit. Kirk and Picard always joins Away Teams whenever possible, which means that the leader is not a lard-bottomed armchair general.
Hierarchy is merely something to fall back on. The leaders and commanders are there to guide, not impose. I know it's a nightmare to some people, but by that time, those people would have failed evolution anyway.
I don't like Battlestar Galactica, but have a soft spot for Babylon 5. SeaQuest DSV sucked. Above and Beyond also sucked. And now, I have Firefly. I haven't watched it yet, and hope it's okay.
No one has done proper sci-fi like Star Trek, though.
