How will people buy the stuff that gets produced if they have jobs and therefore no money?

This is definitely not something that I advocate, but if you have a world in which machines mine iron ore, produce steel, manufacture cars, drill for oil, refine oil, and dispense gasoline -- then you can build a Communist world in which no one works, no one owns anything, no one has money, no one buys anything, but people have "stuff".
I think more automation/less jobs leads us right into more socialism/communism. Lack of money won't be a factor for getting "stuff".
Again: Not where I would want us to go, but it sure looks like we're heading there -- 94 million Americans not in the work force, and government subsidies for all kinds of people all across the land. It will get much worse; because it can.
