How can we in the modern world get along without money? This is, I think, the essence of Maju's question. And maybe the simplest answer is: well, we're going to find out. Real soon now. Whether we like it or not. Because the meaning, and value, of our money is dissolving before our eyes. It could take the form of runaway inflation but there are other forces that could also come into play that would do the trick -- such as a complete and total meltdown of the stock market.
Regardless, there's no question that we can survive in an economy without money, at least without money as we now know it. What's important even in our present situation is not really the shuffling around of money (as in the shell game run for so long by our beloved plutocrats) but the production and allocation of resources. One way to think about it is to think about what happens when someone with health insurance goes to the doctor. Money need not change hands (though in some cases there might be a small co-pay). You show someone your membership card, they sweep it through a little box and you're good.
But what about the doctor, won't he insist on being paid with money? Only if he's a fool. Because in the economy we are now headed for, he'll have no way of knowing what his money is worth, and its value will certainly deteriorate over time. Much better to be presented with a piece of paper telling him that he now has the right to continue living in his home without having to worry anymore about a mortgage; that he can forget about his car payments because the car he's been paying on is now available for his use whenever he needs it; and he can get all the gas he needs simply by presenting a ration card at the gas station.
Of course, such a system will require a huge bureaucracy to run it and there is always the danger of inefficiency, unfairness and corruption. Just as there is now, and always has been, regardless of whether we are living in a "free market" system (in which every large business has a bureaucracy of its own) or a socialist system. There is one very real rub, however. Because it's going to take time to set up such a system and make it work. Which is why it's important to start planning it now.
Is this an idealistic way of thinking? I've been accused of being an idealist. But I'm not. It's a realistic way of thinking. Unless anyone has a better idea of how to deal with our present, ever expanding, catastrophe. If so, please by all means comment below.
