The problem with that analysis is that during our history, a large increase in the supply of either gold or silver raised havoc with our economy; and when there was too little gold around to provide us with an adequate money supply, our economy suffered -- that's why countries like the US and France, which stuck to the gold standard as long as possible, suffered worse than countries like the UK, which abandoned it during the 1920s. Then, look at Spain -- all that gold and silver extracted from the new world didn't make them into a world power. In fact, it did the opposite.

Another factor to consider is the supply of gold and silver in today's world. It's getting harder and harder to get the stuff out of the ground; and the countries which still produce a lot of it have enough of it so that they could, if they so chose, manipulate metal prices (and thus our money supply) just like OPEC does with oil. Sorry -- but after having seen gold and silver soar in price since 2008, and then give back over half of the gains, I don't buy the premise that a silver-backed dollar would remain relatively stable.
