An excerpt from Dave Barry?s Money Secrets, via NPR:

The problem was that gold is too heavy to be constantly lugged around. So, to make it easier for everybody, governments began to issue pieces of paper to represent gold. The deal was, whenever you wanted, you could redeem the paper for gold. The government was just holding your gold for you. But it was YOUR gold! You could get it anytime! That was the sacred promise that the government made to the people. That’s why the people trusted paper money. And that’s why, to this very day, if you?an ordinary citizen?go to Fort Knox and ask to exchange your U.S. dollars for gold, you will be used as a human chew toy by large federal dogs.
Because the government changed the deal. We don’t have the gold standard anymore. Nobody does. Over the years, all the governments in the world, having discovered that gold is, like, rare, decided that it would be more convenient to back their money with something that is easier to come by, namely: nothing. So even though the U.S. government still allegedly holds tons of gold in “reserve,” you can no longer exchange your dollars for it. You can’t even see it, because visitors are not allowed. For all you know, Fort Knox is filled with Cheez Whiz.

Dave Barry comes closer to the truth when he’s being funny that most policy types when they’re deadly serious.
