Yes, the biggest part of the Star Trek Universe was communist in the purist form. The United Federation of Planets eliminated money, and all beings within the Federation worked for the greater good. So in theory, there were no lazy people (bullshit). And everyone got everything that they needed. Some planets outside the federation still dealt in money, like the Ferengi, I think the Klingons did too.

In the Movie, the Voyage Home, Kirk mentions that we still used money. A hint that money was eliminated well before the Next Generation. I refuse to think anything made after Voyager as cannon.

DS9 was shit, and the new series with all those leftists in it is all shit. The movies with the alternate timelines in it is all shit.
