@hawkeye10,
Is that so? What does the richest people in the world have as assets? It's called stocks in businesses. They trade on the open market almost every day - worldwide. If they want cash, all they need to do is sell some shares.
Do you have that flexibility on gold, silver, and diamonds? At what cost? Don't forget commissions, and capital gains taxes, when you trade.
So, when the total gold market begins to sell, how much will gold be worth?
Have you ever studied supply and demand of any commodity?
