Star Trek is communist.
The defining feature is that the way for anything is either reduced to the ability to provide it at the lowest level to all OR to increase ability to give anything to anyone at anytime.
End result of the Star Trek method is that unless you're flying around on a space ship you better be a scientist or an artist because there is no place in society for you.
Communism is an intellectual paradise, as long as the needs of the many are provided to them.
I'm not convinced that giving everyone everything will result in any quest for self improvement.
Star Trek is an excellent example for me. Yes the day to day needs are met so the competition simply moves to other spheres (achievement, rank, status). There can only be one ship captain so competition is fierce. The pressure starts from the academy, students are under massive pressure to perform from a young age.
