It's hard to get more cartoonish than Star Trek's Ferengi, a left-wing caricature of capitalists, going so far as having pointed teeth.

Also, you may want to read what I wrote again. I said "Star Trek is not pretending to be a moral philosophy." Ayn Rand claims that Objectivism is the basis for ethics, epistemology, metaphysics, etc. How on Earth does that compare to the Ferengi being greedy as a parable of capitalism?
I gave a link showing it was Roddenberry's directive. Also, what do you think of the Prime Directive? (Which, of course, is routinely violated if the aliens don't conform to progressive ideals.)

I've read progressive newspaper columnists citing Star Trek as a model to emulate.
