How is my post wrong? Name one fiat currency in the history of the world that has not eventually been devalued and become worthless over time. Every currency that has crumbled has had one thing in common - it used to be backed by gold, silver, or some other precious resource, and then due to the need of government to print more money, the backing was removed. Why are we as humans destined to learn this lesson the hard way every few decades? Because people have a short memory and forget history. Once confidence in a currency has eroded no amount of it can be worth almost anything. See Germany during the Weimar republic - people carrying wheelbarrows full of paper bills to buy a loaf of bread. I'm not saying that's going to happen tomorrow in the US, but currency devaluation is a slippery slope and it is happening all around us.
