At the heart of big-city exoduses is a process that I call accumulative decay. When schools are rotten and unsafe, neighborhoods become run-down and unsafe, and city services decline, the first people to leave are those who care the most about good schools and neighborhood amenities and have the resources to move. As a result, cities lose their best and ablest people first. Those who leave the city for greener pastures tend to be replaced by people who don’t care so much about schools and neighborhood amenities or people who do care but don’t have the means to move anywhere else. Because the “best” people — those who put more into the city’s coffer than they take out in services — leave, politicians must raise taxes and/or permit city services to deteriorate. This sets up the conditions for the next round of people who can do better to leave. Businesses — which depend on these people, either as employees or as customers — also begin to leave. The typical political response to a declining tax base is to raise taxes even more and hence create incentives for more businesses and residents to leave. Of course, there’s also mayoral begging for federal and state bailouts. Once started, there is little to stop the city’s downward spiral.
Intelligent mayors could prevent, halt and perhaps reverse their city decline by paying more attention to efficiency than equity. That might be politically difficult. Regardless of any other goal, mayors must recognize that their first order of business is to retain what economists call net positive fiscal residue. That’s a fancy term for keeping those people in the city who put more into the city’s coffers, in the form of taxes, than they take out in services. To do that might require discrimination in the provision of city services — e.g., providing better street lighting, greater safety, nicer libraries, better schools and other amenities in more affluent neighborhoods.
As one example, many middle-class families leave cities because of poor school quality. Mayors and others who care about the viability of a city should support school vouchers. That way, parents who stay — and put a high premium on the education of their children — wouldn’t be faced with paying twice in order for their kids to get a good education, through property taxes and private school tuition. Some might protest that city service discrimination is unfair. I might agree, but it’s even more unfair for cities, once the magnets of opportunities for low-income people, to become economic wastelands.
