After the dramatic collapse of the Minneapolis freeway bridge last week, the collective hand-wringing began. The bridge was known to be faulty, but had not been replaced. Our entire public transit system is underfunded, we were told.

In addition to transportation infrastructure, those concerned with urban issues have a litany of complaints about American cities. Our transit systems are not adequately linked to zoning laws. Our high parking requirements doom alternative modes of transit and drive up development costs. Our policies encourage uncontrolled sprawl, which seemingly nobody likes. Planners' recommendations are too often overruled by ill-informed and politicized zoning boards. Our buildings aren't energy efficient. City mayors and councils play politics with projects painstakingly approved through highly democratic review processes. And nobody's happy when local activists hold undue power over individual projects.

The solutions we are given are almost as varied as the problems. More centralized planning is often called for, or perhaps more regional planning. However, this seems highly difficult and unlikely in most places where land use is regulated by many small municipalities. Some suggest the solution is more public input on infrastructure and private projects to enhance their quality, while others think we need less input to speed them along and reduce the costs incurred by delays. Some are convinced elaborate flexible or form-based zoning holds the key to better cities, although implementation seems frustratingly difficult. Some cynics conclude that perhaps it is American cultural biases that produce our flawed cities: maybe Americans just like it this way, living with decaying infrastructure, long commutes, but low taxes.

The motley list of solutions almost never includes the one thing that actually has overcome the myriad of obstacles to good city building before: a broad-based and robust conversation to create solutions, money, and political support.
