Aside from the occasional invasion by the Borgs, Romulans, Cardassians or warring Klingons, Star Trek's vision of life in the 23rd and 24th centuries is pretty sweet. As Jean-Luc Picard put it in The Next Generation: "A lot has changed in three hundred years. People are no longer obsessed with the accumulation of things. We have eliminated hunger, want, the need for possessions. We have grown out of our infancy."
