It’s important to draw a distinction between what a work of art tells you and what it shows you. In the world of Star Trek, there are a few, infrequent references in which we are told that the economy works (somehow) without prices. But the socialism all happens quietly off screen, and it’s not what the show is actually about. The show is about the culture and approach to life of those on board the Enterprise (or the other vessels in later spin-off series). And the culture of the Federation bears none of the hallmarks of a socialist society.

When people are provided with a guaranteed living, whether they work or not, they don’t generally devote themselves to self-improvement, the betterment of mankind, the writing of deathless poetry, or the peaceful exploration of the galaxy. Instead, they tend to stop working, striving, or putting forth any effort at all, not even the effort of changing out of their pajamas in the morning. To the extent they do work, since effort has been disconnected from reward, they tend to avoid as much effort as possible. In the Soviet Union, there was an old joke: “We pretend to work, and they pretend to pay us.” And when rewards and advancement are no longer connected to a person’s productivity, they tend to be distributed according to an alternative currency of political pull. So all organizations end up being run by preening politicians, scheming bureaucrats, and drone-like functionaries who are skilled at pushing paper and going through the motions of production rather than actually producing anything.

What we are shown on Star Trek is the opposite.
