Thoughts from Ilya Somin:
Instead, it is the Federation that turns out to be a sort of kinder, gentler Soviet Union. Both are multicultural, federal, socialist states with an official ideology of egalitarianism. But the Federation lacks the Gulags, secret police, and mass murder (or at least we never see them on-screen!). Meanwhile, the Romulans represent several of the negative qualities that many leftists associate with the present-day West: elitism, arrogance, and intolerance for other cultures. The same can be said of many other Star Trek villains, such as the Ferengi, who represent the supposed evils of capitalism. At some level, of course, Star Trek is a projection of Western values. After all, egalitarian socialism is a Western ideology. However, Trek is far more hostile to the present-day West than Nussbaum and some other left of center critics recognize.
Some say Roddenberry was a dreamer. But (sadly) he’s not the only one. Imagine.
