The sky is falling! Or something. OK, OK, the increase in food prices is a reality. But if you need to read stories about Americans stockpiling and hoarding foodstuffs such as rice and flour, the Chicago Tribune has one, U.S. News & World Report has one titled "Should Shoppers Hoard Rice?" and the Wall Street Journal has one titled "Load Up the Pantry" (I kid not).
Certainly, some degree of stockpiling was already going on, but the media is fanning the flames by running these much too-easy-to-write stories (send a reporter to Sam's Club! interview a man on the street!). And frankly, it's a little irresponsible. Literally instructing people to stockpile is only going to make matters worse.
Now hurry up and get yourself to Costco!
