So what do we call the continuous printing on our gumt's presses, when there is nothing to stand behind it but a (less than) worthless IOU?
Money is now a 'commodity' traded on the market.
It isn't a tradition 'IOU' as was given when you gave something to someone with a promise it would be paided in the future.
It is a 'good' that is traded in exchange for a product or service.
In and of itself, that is not a problem because it's easier to carry 'dollars' around then a truck load of chickens, or pigs or whatever you want to 'barter' with.
The problem comes when the Government decides it needs more 'bargaining power' and prints excess dollars which flood the market.
That drives the dollars value down, and in return, ends up hurting everyones bargaining power and reduces the value of their 'goods'.
