Quote from gnome:
There isn't any genuine NEED for a currency to be backed by gold.. it's just that gold holds the evil doers' "feet to the fire" so to speak.
About 25 years ago on Wall Street Week, I heard Milton Friedman decry the Fed and say, "The Fed should be abolished and be replaced with a computer... one which increases the money supply at the same rate as the population growth... about 2% per year".
If we had such a plan and could rely upon its honesty... PLUS the Federal Government were forbidden from spending in deficit, there would be no need for our currency to be backed by anything other than the government's tax-levy authority.
You got it.
But like I told the OP earlier, such a system will always be corruptible and Bankers will find a way to rig the money supply.
A constitutional amendment? Don't think so.
There would never be enough voters in the Country who could understand its necessity.
Further, if it passed, Wallstreet would find a way to corrupt the Bureau of Labor and Statistics to cook fake numbers (they do it already on their own accord) to ramp booms and busts.
Like Gnome said, the problem is not an economic one. But a human one. Human nature to be precise.
So whats the best system?
Commodity-backed, I think. Its the only currency that cant conjured.
