"Grocery money is an odd sticking point for U.S. citizens, who on average spend a lower proportion of our income on food than people in any other country, or any heretofore in history. In our daily fare, even in school lunches, we broadly justify consumption of tallow-fried animal pulp on the grounds that it's cheaper than whole grains, fresh vegetables, hormone-free dairy, and such. Whether on school boards or in families, budget keepers may be aware of the health tradeoff but still feel compelled to economize on food -- in a manner that would be utterly unacceptable if the health risk involved an unsafe family vehicle or a plume of benzene running through a school basement.
It's interesting that penny-pinching is an accepted defense for toxic food habits, when frugality so rarely rules other consumer domains. The majority of Americans buy bottled drinking water, for example, even though water runs from the faucets at home for a fraction of the cost, and government quality standards are stricter for tap water than for bottled. At any income level, we can be relied upon for categorically unnecessary purchases: portable-earplug music instead of the radio; extra-fast Internet for leisure use; heavy vehicles to transport light loads; name-brand clothing instead of plainer gear. "Economizing," as applied to clothing, generally means looking for discount name brands instead of wearing last year's clothes again..."
"Buying your goods from local businesses rather than national chains generates about three times as much money for your local economy. Studies from all over the country agree on that, even while consumers keep buying at chain stores, and fretting that the downtown blocks of cute mom-and-pop venues are turning into a ghost town. Today's bargain always seems to matter more."
