> There is a big difference between using gold and silver for currency--which people did for thousands of years--and a gold- or silver-backed paper currency, which only existed for a couple hundred years at most. I know gold standard fans like to equate them, but they are not the same thing at all.
That's a very interesting point! I think I "knew" that they were different without ever putting it together like that. It's obviously true though, there were a number of years here in the US when you could own dollars but not the gold that the dollars supposedly represented. http://en.wikipedia.org/wiki/Executive_Order_6102
> Gold and silver used as money were actually a form of barter.
I'm not sure I agree with that but it's probably semantics. Is gold "money" or "commodity" and why? There's no obviously right answer. If people did bookkeeping in ounces of gold and paid their taxes in ounces of gold, doesn't that make it "money" in the sense that we would use today?
> Fiat currency is resistant to such manipulation because no one can ever control enough of it to manipulate the economy. The government can create or destroy as much as it needs to.
So it's not clear to me that granting the government (technically the Federal Reserve which is privately owned and truly only answers to its owners) control over the economy the way we have is actually a good thing. You still have an entity that can manipulate prices and the economy, it's just most people accept this as a good thing without any thought at all. Most people probably still believe that the gold inside Fort Knox or the Federal Reserve banks are somehow meaningful and in some way related to our money; but they aren't. You've traded the possibility of someone manipulating the economy in a harmful way for the certainty that someone will manipulate the economy but with the outcome unknown at any time.
The Fed still does price fixing, by the way. They fix the price of money, or as most people call it, the interest rate. Because their balance sheet knows no limits they can buy or sell as much of anything as they want until the interest rate is the "right" one as decided by a bunch of people who don't have a lot of connection to the real economy anymore.
You might argue that the Supreme Court is similar (unelected and generally unaccountable) but there's a difference. The people on the Supreme Court can make decisions based on existing law and precedent and legal arguments brought before them. And it's fairly easy for the Congress to override their decisions if they're particularly egregious since they publish opinions that explain their reasoning.
As it stands there's really no feedback mechanism for the Federal Reserve short of writing new laws that change the entire system. None is built in. Sure they have to go before Congress twice a year, but they can't be fired for policy opinions. It's a sweet gig if you can get it, but it's kind of insane just how much power these folks wield and how little accountability they face for their actions.
