A guy from the World Food Program said "Food might be there on the markets, but people don't have the resources to buy it because it is too expensive."
I am not worried about MY access to food. However I am worried about world stability. The reason I am not worried is that I am, at least relative to the entire world, rich. Like most Americans and western Europeans I spend a relatively small percentage of my income on food. If food prices go up 15 or 20 percent I would notice and grumble but could easily pay. If food prices went up 100 percent or even more we would change the way we eat and have to adjust our budget but we would be able to afford some sort of food to eat.
However food prices radically going up screws with a lot of people. Poor folks (and I'm talking 3rd world poor not those whining Americans with a comfortable residence, 2 cars, flat screen TV's and an Ipod's) can't do this. They spend a very high percentage of their income on food. They don't have room to shift things around if food prices go up 30 percent, let alone double. This means they need to earn more money which is not a solution because if they were capable of that they would already be doing it. What it really means is that some people might starve and lots of people will start protesting and burning stuff down. These folks are ripe for getting whipped up by political agitators of all kinds as they are in a bad spot as well as generally being poorly educated and often illiterate. This is the kind of stuff that, if left unchecked can topple or radically reshape countries. In particular Mexico (not that it is the most vulnerable but by proximity it would have the biggest second and third order effects on the US) is quite vulnerable to changes in corn prices.
Something to pay attention to if not to freak out about.
