Star Trek is definitely Communist (or fascist). Star Wars universe seems mostly pathetic. Most of the planets seem to live like The Flintstones only with rocket ships and cool weapons.
Ask Sheldon Cooper?
Probably showing my inner geek, but I remember reading some of the Star Wars Extended Universe material where they explained the reason for that. Humans (or the humans of the Star Wars Galaxy) where the first species to discover hyperspace travel something like 100,000 years before the current time-line. Humans then colonized much of the galaxy, while they would engage in limited trade and contact with alien life forms they encountered, they refused to provide the secret of hyperspace travel and other advanced technology. So aliens were stuck in their home systems and greatly limited technologically. It was only in the last 10,000 years or so that hyperspace travel began to spread among other species. That is why, in the Star Wars Universe the movies are set in, Humans are still, by far, the largest and most dominant species and have colonized many worlds across the galaxy, while alien species, for the most part, are still limited to their home systems. That also explains why you see vastly different technological levels, even among alien and human residents of the same planet.
“Star Trek is definitely Communist (or fascist).”
Disagree. What about it is communist or fascist? The economic system in Star Trek is not like anything we have now because there is no real need for money. All basic human needs and wants can be created out of energy, and energy is essentially free. People dont need to work, but just about everyone does for personal fulfillment (in real life few would bother to get off the couch). There is a govt and an exploratory/defense force (Star Fleet) but role and workings of govt is not made clear. It certainly doesnt seem oppressive and everyone seems to be free to do what they want (within limits).
