You're overlooking the fact that there are an awful lot of people who simply can't afford to buy any but the cheapest food, however unethical. When it comes to a choice between barely feeding your kids or being politically correct (and I don't mean that in a negative sense), then there's no choice. Granted, some people chose to be parsimonious -- they are open to persuasion, but there are those who don't have the luxury of choice. I now I'm starting to sound like my dad now, but there just ain't any simple answers!
