Why use gold to preserve wealth?
"Meanwhile, gold waits in the wings. Most latter-day economists place gold in the category of "just another commodity." I disagree. I place gold in the category of true money. Every other commodity is consumed, "used up" over time. Gold is accumulated -- nobody destroys gold. Even old dental crowns are collected, melted down, and sold for cash. Unlike other commodities, there's always, at any time, an unlimited market for gold.
This doesn't mean that currencies can't fluctuate against gold. Over recent years, we've seen where it takes 250 dollars to buy an ounce of gold and more recently it's taken over 700 dollars to buy an ounce of gold. A few years from now it may take several thousand dollars to buy an ounce of gold, since so many dollars are in the process of being created. We just don't know, at any given time, how many dollars it will take to buy an ounce of gold, but I can tell you this -- gold has outlasted every fiat currency. And as night follows day, gold will outlast the dollar."
