Derp. Youve never heard of inflation? And the entire worlds known gold supply could could fit in a cube 20m x 20m x 20m (per wikipedia). Even if hundreds "meteor(s) full of gold crashed on earth" it would never approach the inflationary effect that has occured in currency around the world and the US.
With nearly 15 trillion dollars in debt against our "full faith and credit", and growing by 1.5 trillion+ recently, it may very well take a cube of 20m of cash on all sides to buy an ounce of gold.
This is what has driven the overheated speculation in gold and ESPECIALLY silver. The world's debt delima.
A balanced budget would slam precious metals hard. Until then, the skys the limit because we cant get our financial house in order to save our lives, even if it means default.
