Buying Into the Company, Not the Commodity - New York Times
Simply suggesting that it is worth buying the companies that deal in commodities vs. the futures, less volatility, etc., and in the long term, the cost of goods will rise. Population up, Urban area up, commodity prices up, plus, science is coming up with new uses for corn, petroleum, and everything else every day. Gold and Silver are interested, but it would make sense that as wealthy classes increase there will be a continued demand for precious metals.
I wonder how important the notion of tying money to precious vs. untied currency really matters anymore with such a globalized market place that will gladly slam a county of inflating its money supply.
