The best marketing campaigns skip past our head and land on our heart. In that regard, few have been as successful in recent years as the "buy local" movement springing up in metropolitan areas around the country.
The essence of what I'll call localism is this: Our economy will be stronger and our life richer if we spend more of our money at or with independently owned businesses in our own communities, even if it means paying higher prices.
The emotional appeal of that argument is undeniable. But the same rationale -- protecting jobs and standards of living for particular groups -- has been used for centuries to justify everything from punitive taxes on imports to Buy American mandates -- always at the expense of consumers.
Example: "voluntary" trade restrictions by Japanese carmakers in the 1980s. They didn't save the U.S. auto industry, notes author Todd Buchholz, but they boosted car prices by an average of $3,000.
I live in a neighborhood with many locally owned businesses, and I feel better when I am able to spend money with merchants I've come to know and trust. But to insist that those purchases are better for the economy than ones made at Best Buy or Target suggests a shaky grasp of economics.
The localism movement is a distinctly urban or small-town phenomenon, closely associated with the environmental and organic food movements. It began to coalesce two decades ago, out of efforts to block the arrival of Wal-Mart and other big-box retailers.
Few have been as vocal or effective in this fight as Stacy Mitchell, a Macalester College graduate and senior researcher with the Institute for Local Self-Reliance, which has offices in St. Paul and Washington.
In her 2006 book, "Big-Box Swindle," Mitchell likens Wal-Mart and its kin to the colonial economies of Europe, which were organized to extract wealth from local inhabitants, not improve their lives.
