STAR TREK is about "strange new worlds" and civilizations, not one enlightened universal society . . . .[/QUOTE]
Roddenberry mentioned many times that a large part of Trek's appeal is that it shows a very positive vision of humanity's future, which was a very profound message during the tumult of the sixties and seventies and even during the Reagan era with Cold War tensions, environmental and hostage crises at the forefront.

I still say Roddenberry was imagining a society beyond this. Also, Gramsci was on to something when he described "cultural hegemony" and how it used popular culture to mould public consciousness.
