The $1.60 a day I’m paying for three meals a day here is a bargain only by the narrowest of calculations. It doesn’t take into account, for example, the cost to the public health of antibiotic resistance or food poisoning by E. coli O157:H7. It doesn’t take into account the cost to taxpayers of the farm subsidies that keep Poky’s raw materials cheap. And it certainly doesn’t take into account all the many environmental costs incurred by cheap corn.
