I mean, at the end of the day Star Trek is a capitalist product written by capitalists meant to appeal to an audience raised to believe in the absolute moral good of capitalism. Every now and they might sneak in a sly and gentle anti-capitalist criticism (the Ferengi were good for that) but no one actually wants to alienate their audience.

I don't think it's quite that capitalist.

Picard says at one point "A lot has changed in three hundred years. People are no longer obsessed with the accumulation of 'things'. We have eliminated hunger, want, the need for possessions."

At another point he says "The acquisition of wealth is no longer the driving force in our lives. We work to better ourselves and the rest of humanity."

To be fair, capitalism is mainly a system of contracts and laws that allow for certain kinds of ownership structures and investments. It does not necessarily have to be done in a way that is obsessed with the accumulation of things or wealth. So those quotes are also not really anti-capitalist. But the quotes are, at least, not friendly to today's common notion of what 'capitalism' means.
