Guys, I think the situation is that there are multiple factors causing the increase in prices (food, in this case).
Factor 1: supply & DEMAND. Jim Rogers talks about the commodity bull market all the time. He points out that developing countries are getting wealthier, and want to eat more/better. More meat, for example. Well, producing meat takes a tremendous amount of grains (something like 7x?)... much more than was required when the poor guy in China was only consuming rice. This is happening throughout the world in developing countries... from food, to energy (more cars, construction, etc..), to basic commodities (steel for building). Demand -> tremendous growth.
Factor 2: SUPPLY & demand. The supply, in many cases has been shrinking the past 30 years. Jim Rogers also points out that many commodity stores/production are at 20, or 30-year lows. He talks about wheat stores being at 25'ish year lows. That certain types of mines have not been opened in 30 years, and that it takes nearly 10 years to get a new mine online. This low supply, in many cases, is a direct result of the 30-year bear market in commodities. As prices increase, market dynamics will lead to increased supply, but IT TAKES TIME, and cannot happen overnight. It takes a decade in some cases, which is why commodity bull markets usually last 15-22 years.
Factor 3: The U.S. Dollar. The U.S. Governement is spending beyond its means. The Fed is debasing the dollar, and always has. To do this they are creating money. The only reason US Bond yields are so low (asked by someone earlier) is because the Fed is directly buying them now in order to keep rates low. If the market was allowed to work, rates would be much higher. There is no doubt that inflation is occurring, and has been much higher over the last 20 years than the government stats claim. John Williams at Shadowstats.com has good data showing this. Only someone unfamiliar with the details of the calculations (or in denial) would deny this fact.
So, we are looking at a Double (or triple) whammy. Supply & Demand are going to force higher prices, and the debasing of the US Dollar will continue to result in higher prices (actually low purchasing power of the dollar).
The two are NOT mutually exclusive. It's ridiculous that you guys are arguing that it has to be one or the other...
IT'S BOTH
