Most government plans are so full of fabrications and unsupportable assumptions that they aren’t worth the paper they are printed on, much less the millions of tax dollars spent to have them written. Federal, state and local governments should repeal planning laws and shut down planning offices.
Everybody plans. But private plans are flexible, and we happily change them when new information arises. In contrast, special-interest groups ensure that the government plans benefiting them do not change — no matter how costly. Like any other organization, government agencies need to plan their budgets and short-term projects. But they fail when they write comprehensive plans (which try to account for all side effects), long-range plans or plans that attempt to control other people’s land and resources. Many plans try to do all three.
Comprehensive plans fail because forests, watersheds and cities are simply too complicated for anyone to understand. Chaos science reveals that very tiny differences in initial conditions can lead to huge differences in outcomes — that’s why mega-projects such as Boston’s Big Dig go so far over budget.
Long-range plans fail because planners have no better insight into the future than anyone else, so their plans will be as wrong as their predictions are.
Planning for other people’s land and resources fails because planners will not pay the costs they impose on other people, so they have no incentive to find the best answers.
Most of the nation’s 32,000 professional planners graduated from schools that are closely affiliated with colleges of architecture, giving them an undue faith in design. This means many plans put enormous efforts into trying to control urban design while they neglect other tools that could solve social problems at a much lower cost. For example, planners propose to reduce automotive air pollution by increasing population densities to reduce driving. Yet the nation’s densest urban area, Los Angeles, has only 8 percent less commuting by auto than the least dense areas. Meanwhile, technological improvements over the past 40 years, which planners often ignore, have reduced the pollution caused by some cars by 99 percent.
Some of the worst plans today are so-called growth management plans prepared by states and metropolitan areas. They try to control who gets to develop their land and exactly what those developments should look like, including their population densities and mixtures of residential, retail, commercial and other uses. About a dozen states require or encourage urban areas to write such plans. Those states have some of the nation’s least-affordable housing, while most states and regions that haven’t written such plans mostly have very affordable housing. The reason is simple: Planning limits the supply of new housing, which drives up the price of all housing.
In states with growth management laws, median housing prices in 2006 were typically four to eight times median family incomes. In most states without such laws, median home prices are only two to three times median family incomes. Few people realize that the recent housing bubble, which affected mainly regions with growth management planning, was caused by planners trying to socially engineer cities. Yet it has done little to protect open space, reduce driving or do any of the other things promised.
Politicians use government planning to allocate scarce resources on a large scale. Instead, they should make sure that markets - based on prices, incentives and property rights — work. Variably priced toll roads have helped reduce congestion. Pollution markets do far more to clean the air than exhortations to drive less. Giving people freedom to use their property, and ensuring only that their use does not harm others, will keep housing affordable.
Unlike planners, markets can cope with complexity. Futures markets cushion the results of unexpected changes. Markets do not preclude government ownership, but the best-managed government programs are funded out of user fees that effectively make government managers act like private owners. Rather than passing the buck by turning sticky problems over to government planners, policymakers should make sure markets give people what they want.
