Some retarded info going around in this thread.
The dollar is not ‘not backed by anything’. It’s backed by a right to pay debt, most importantly a right to pay U.S. income tax debt. That is value, whether or not that value is comparable to gold or silver is a matter of opinion. But to compare it to points in a video game is retarded.
Timmy has five apples. He can choose to eat the apples or he can trade them to Bobby in exchange for doing his homework. Ari suggests that he hold on to the apples and draw up "Apple Certificates" so that the certificates can be traded for homework jobs back and forth without causing wear and tear on the apples and to save on having to carry them around. Ari offers to redeem the certificates for apples whenever someone wants. This works for a while and "Apple Certificates" are freely traded for small jobs between classmates. The success of the certificates is lauded by everyone; the velocity of certificates soars and a cottage industry of homework cheating springs up. The entire class holds the "Apple Certificates" to have essentially the same value as the apples, and since they can be redeemed at any time, they place a lot of trust in the value of them.
Then one day, Ari decides that the "Apple Certificates" are so well trusted in the classroom economy, and that because basically nobody is actually coming to redeem apples from him, that he will save a step and not even bother to redeem apples anymore. The class grumbles at first, but they are so used to dealing in "Apple Certificates", and there is no real other option, so they just keep on with the status quo.
A few days later, it dawns on Ari; why not just create new "Apple Certificates" at will? Nobody will do anything about it. The class is so preoccupied with lessons and homework assignments that they don't have the time or the patience to argue with Ari about his little venture. And so he does. At first just one a week, which he uses to pay for Timmy to do his homework for him. He rationalizes this to himself and to his classmates as a good thing--after all, Timmy is now 1 "Apple Certificate" richer than he was before. Ari pats himself on the back and life goes on.
But, before too long, Ari gets greedy. It starts out slowly. He buys a candy bar from Bobby one day, and then pays Timmy to do his homework for him again the next. Pretty soon, he is making a new "Apple Certificate" every day. The class takes notice of the influx of certificates into their little economy and starts to demand two certificates for each homework assignment. And then soon after, four. Soon after that, 10. In short order the class is swimming in "Apple Certificates" and the class can barely keep up with the increases. Timmy, at one point having offered to do Bobby's homework for the rest of the semester for the price of five "Apple Certificates", is really feeling the pinch. He only has two left, and he can't even buy a candy bar with that anymore. The rest of the class quickly finds themselves in the same predicament. Their "Apple Certificates" are nearly worthless and their previously-agreed certificate loans are quickly proving to be a huge problem as time goes on.
At one point, in the middle of a squabble between Bobby and Timmy about debts owed, the teacher intervenes. He inquires about the reason for their argument and upon finding out the reason says "You know, this all started when you let Ari start issuing "Apple Certificates" at will, why don't you guys take it up with him? At that point the class has a moment of clarity about a number of problems that have befallen the class as of late. The problem all along was Ari! How could we be so stupid?
That afternoon, the class waited outside the school building for Ari and then hung him from a tree.
