The ratio is rapidly changing as more and more uses for gold are being found. It is the number one material of choice for electrical connections and new nano particle uses are on a tear...
Only yesterday I saw a new technique for using gold nano particles in human waste disposable. Who knows what future uses may be.
We have QE3 continuation, 4% monetary growth, real price inflation, debt monetization that are all positives. The one future negative might be real interest rates. Right now they are negative, which is good for gold. But will interest rates rise sharply enough to produce a positive real rate of return?
