What if gold became the currency for the US... or anywhere else for
that matter?
Check out Saville's article on gold, inflation, and monetary policy on
greenfaucet- called "returning gold to money". This guy discusses how
to get gold from where it is now to a form of money and whether or not
gold will become the unit of exchange in the near future.
I can't see it happening anytime soon-- It would take a complete
overhaul not only of the government and the Fed (which would be gone)
but also of culture, lifestyle, etc.
I think the general public would be far too uncomfortable with gold as
the unit of exchange. A more likely future? A new currency.
