Just read this article, about a new book that articulates Star Trek's money-free society -- the idea of a post-scarcity society where material wealth has become so abundant that people and society at large are guided by other motivations. While the article is still occasionally mired in conventional views of human motivation (competition), it did remind me of a Star Trek video clip I once posted on this very theme...



(I also posted an extended clip later, if you're interested in the storyline.) 

BTW - I disavow the ads Google occasionally places on these videos - it's not my doing.
