I'm going to dumb it down a bit, and say that I like to think of two movies with different visions of a technologically advanced future: WALL-E and Elysium (aka that Matt Damon movie where all the rich people live on the space station). In WALL-E, nobody works and everybody (well, everybody that survived the initial apocalypse anyway) lives the literal fat life while robots serve them all equally. In Elysium, the abundance of health and life that comes from technological advances are hoarded away for exclusive use by the wealthy.

Of the 2 visions, I always found the Elysium model to be much more likely...actually I would argue inevitable. Given human nature, I just can't foresee a world where everyone lounges around in equally-served harmony. No...there will always be an elite, and the elite will find a way to procure and consume a vastly disproportionate amount of resources. Even in the movie Elysium, after the proletariat storm the space castle at the end, any "victory" will be short-lived and will just produce a new elite.

So I guess I'm suggesting that the proclaimed political/economic system is irrelevant. The reality ends up looking pretty much the same in either case. And that reality will probably not be pretty once human labor is fully commoditized through technology.
