This is an excellent video that I would encourage all of you to watch. It provides a visual look at city finances and explains how car-dependent suburbs are usually heavily subsidized by productive urban places. These are the kinds of analyses that all cities should be doing and, among many other things, I think it could go a long way to positively influencing how we plan our cities. Want to keep densities low and new development to a minimum in your community? Well then you should expect to see a commensurate increase in property taxes. If that doesn’t make sense to you right now, it will once you watch the video.
