What's even more ridiculous is what these "dollars" represent. No one is on the gold standard anymore, so money only has value because we believe it does! Dave Barry once compared it to that scene in Peter Pan where we're told that Tinker Bell will come back to life if we just believe hard enough. That's our financial system! It's the Tinker Bell system! And we thought the cattle-based monetary system of ancient times was silly.
It's not like the gold standard is
any different. Gold only has a certain value because we say it does. It's the same "Tinker Bell" phenomenon, really.
ANY economy is going to be based on faith. The instant a farmer stops cutting his own hair to spend more time growing food then he is proclaiming faith in the idea that someone else will be willing to cut his hair in exchange for food at some future point. He's putting faith in the system.
There's really no way around it.
