Today's guest on Economics Detective Radio is Chuck Marohn, founder and president of Strong Towns. Strong Towns is a non-profit that seeks to reform America from the ground up, starting with its towns and cities. It aims to promote healthy local economies by improving local governance. The Growth Ponzi Scheme Chuck began recognizing the problems in America's towns and cities when he was working as a civil engineer. He recounts a story of working in a little city in central Minnesota in the late 1990s. The city had a 300-foot pipe that had cracked, allowing ground water to leak in and overflow their treatment facility. Chuck proposed a $300,000 solution to fix the pipe. However, this was a tiny town with an annual budget of $85,000. So Chuck went to higher levels of government (the federal government, the USDA, etc.) to find someone to fund the project. They all said, "This feels like maintenance. We don't have money for maintenance, so you need to pay for this yourself." Since the feds would only fund expansion projects, Chuck devised a plan: He would propose the largest expansion project he could, then repair the pipe as part of the expansion. This wasn't so much deviousness on his part as it was standard practice in his profession. He designed a couple miles of new pipe, doubled their treatment facility, and as part of that he included repairs for the old pipe. This new project cost $2.6 million. Everyone was happy about this project. The grant agencies were happy. The legislators issued glowing press releases and held a big ribbon cutting. Chuck got a big bonus from his company. The city was ecstatic. The only lingering problem was that this tiny city that couldn't afford to maintain 300 feet of pipe would now be left with a few miles more pipe and a larger treatment facility. This is an example of one part of what Chuck calls the Growth Ponzi Scheme. This is when cities and towns expand in ways they can't maintain without further expansion. There's a political reason why things like this happen. Building new infrastructure is very politically appealing. You can build a new highway and name it after a prominent politician, you can have a big ribbon-cutting ceremony, and you can get all sorts of good press for the project. Maintenance is less sexy; you close down a lane of some existing highway, delay everyone's commute, and then you don't have a ribbon-cutting or positive press for all the potholes you filled in. That's why higher levels of government have been paying for big projects and passing off the responsibility for maintaining them to local governments. These local governments become insolvent when the revenue from the initial big project runs out and the maintenance expenses come due. This process leads to a form of development where the local tax base is not sufficient to pay for the infrastructure that supports it. When the expansion can't go on any longer, the infrastructure crumbles, the affluent people leave, and the community ends up locked in poverty. What's Wrong with Big Box Stores? Embracing this form of unsustainable growth has made our cities less dense and walkable. Instead we have heavily subsidized driving as a means of getting everywhere. One consequence of this has been the rise of big box stores. The public debate on big box stores tends to miss the mark. The left says big box stores crowd out local businesses, which is true. The right says they pass the market test, offering lower prices and thus improving poor people's standard of living, which is also true. What both miss is that these big box stores only pass the market test because they don't bear the costs of the infrastructure needed to support them. By subsidizing infrastructure, and by building our cities to be spread out and unwalkable, we make bringing groceries to the people unviable. Instead, the people drive to where groceries are. In addition to the rise of big box stores, we've seen the demise of small town living. While small town
