The Federation in it's usual state isn't Authoritarian by any means. Nor is it communist. Federation technology has moved Humanity into a post scarcity society. 

Since Communism and Capitalism are both strategies for dealing with scarce resources neither applies to the world of Star Trek.

I always find it funny when Leftists lay claim to Star Trek. It's saying that their strategies don't work without limitless resources.

I'd kind of agree on the part of the federation, but you have to keep in mind Star Trek is usually following the flagship of **Star Fleet,** a military organization with rank, file, and even corruption from most of the admirals. 

I'd say on that merit alone it's authoritarian.
