The hope for humanity would be for a simple and money-optional society. Everyone "gets" the basics (food, shelter, simple clothes, education, healthcare, public transportation, maybe a computer with internet access) with no requirement to contribute anything to society. If they want anything more than that (iPod, trip to Disney Land, a car, a house with front yard, clothes other than a solid color t shirt) they will need to make money, and for that they will have to work in one of the few jobs available. These jobs would be almost entirely academic (research will always be necessary), service, or cultural in nature. People would work until they could afford whatever luxuries they want, and then could opt to go back to having free time to explore their own desires/ambition. Without the requirement to work, working conditions would automatically improve, as companies would no longer be able to keep workers if "doing nothing" is better than the job they are offering.
That is possible today actually, if we change the welfare system from something that gives out money to something that only provided necessities, and not money. Instead of farm subsidies, flat out buy the food.
This system would only work if the "public option" for things that was held to a standard that anyone would be willing to accept. What passes for public housing now does not qualify, but what passes for dorms / cafeterias at a public college would be a start.
