Q&A 9, Second Answer

My question is: Is it possible to hypothesise an economic structure wherein nobody is required to work?

Yes, but such a structure would only be ideal in the relatively distant future.  As the world is now, many methods of producing goods are automated; more could be so if people did not protest against mechanical production due to fear of losing their jobs.  If we could make such methods self-sustaining (and we have the ability to do this now; we simply do not because it would upset the current economic structure) we could offer the goods produced by them free of charge, and devote our labour and money to other areas.  This change in economic focus would help accelerate progress, and more systems could become automated.  Working would become less necessary, not only to survive, but to enjoy a luxurious lifestyle.  As a result, less people would choose to work, but that would be okay, because there would be less jobs necessary.  Eventually, all or virtually all careers would no longer exist, because they would all be performed by machinery.  At this point, society could actually become communist, and everyone could enjoy equal fruits of the labour of machines.  However, such a society is currently very far away from implementation, so in modern times, socialism (wherein nobody is required to work in order to survive, but where most people would probably choose to work so that they could enjoy better lifestyles) is a more practical option than communism.
