It’s worth noting that the idealized Main Street is not a myth in some parts of America today. It exists, but only as a luxury consumer experience. Main Streets of small, independent boutiques and nonfranchised restaurants can be found in affluent college towns, in gentrified neighborhoods in Brooklyn and San Francisco, in tony suburbs — in any place where people have ample disposable income. Main Street requires shoppers who don’t really care about low prices. The dream of Main Street may be populist, but the reality is elitist. “Keep it local” campaigns are possible only when people are willing and able to pay to do so.
