Because they’re are multiple storylines about unmitigated capitalism being evil with the plot hinging around replicator technology and the fact the galaxy is not post scarcity. The federation is and several species and organizations are but as a whole the galaxy isn’t. Humans specifically are almost never painted in the best light especially when it comes to capitalism and pre starfleet society.

That’s your opinion and one that is largely hinged on humanity being at it’s core altruistic which btw starfleet does not agree with you on.

Yes it does, the people with the money have the most power, this hasn’t changed and canonically the same is true in universe again they’re major multi series story arks.

even ones who were hesitant such as yourself.

There’s that assumption again, pointing out what is is does not imply support thereof but sure, strawman it up if you feel that necessary.
