**First of all, how do you know how much Gold the US has left? Those numbers are not available to the public thanks to the secretive quasi-private Federal Reserve System. I don’t argue against that there is not much left though… **
The federal reserve is not that secret for those willing to question things and not swallow conspiracy theories whole.

As of March 27, 2008:
Gold stock 11,041 0 0 11,041
That’s in millions by the way.
**Second, you can be on a “semi gold-standard”. “x” number of USD to one oz of gold. Or you could back the currency by silver. **
What’s the benefit of doing such a thing?
**We need some mechanism in place to limit the creation of new money. Otherwise we continue to debase our currency and we’ll have much inflation as a result. **
We’ve had the current process for decades and it has worked well so far. Why would we now “debase our currency” and “have much inflation”?
**Relative to what? Another currency? A USD backed by Gold would have a backing that has a strong financial history to keeping its purchasing power. So our currency would be desirable because there is a mechanism in place (of value) that keeps inflating the currency “in check”. **
I don’t mean relative to anything. Gold is a seperately traded commodity. As such it’s price will rise and fall based upon demand for gold, supply of gold, and a myriad of other reasons. If our currency is tied to gold then our currency must fluctuate at the same levels.
You have to ask yourself the question as to why the price of Gold rose in USD to the extent it did over the past several, more so than many other currencies.
That question is fairly easy to answer. The US is experiencing a slowing economy. As such, the price of gold will rise in comparison. When the US experiences an economic resurgence then the price of gold will fall in comparison to the dollar.
Greenspan had some wise words, both before and after he was head of the Federal Reserve System.
Greenspan’s words are just wind. You’ll note that he (or the fed that he led) should bear a significant portion of the blame for the current housing problems that the country faces. He could have done much to attempt to slow the growth of the bubble, but instead he rode the wave as long as he could and then dumped the problem into someone else’s lap.
So since a Gold standard or any other mechanism that would limit the creation of new money is such a bad idea, what solution do you have to offer? Simply continue inflating our money supply?
I actually don’t see much of an issue with the way that our money supply works. I don’t really like that the fed is currently loaning all of this newly created money, but I see the reasoning for it and understand that these loans are typically very short and when paid back the money is taken back out of the market. That is unless the Fed turns around and loans more.
