https://www.strongtowns.org/the-growth-ponzi-schemethe revenue collected does not come near to covering the costs of maintaining the infrastructure. In America, we have a ticking time bomb of unfunded liability for infrastructure maintenance. The American Society of Civil Engineers (ASCE) estimates the cost at $5 trillion — but that's just for major infrastructure, not the minor streets, curbs, walks, and pipes that serve our homes.
The reason we have this gap is because the public yield from the suburban development pattern — the amount of tax revenue obtained per increment of liability assumed — is ridiculously low. Over a life cycle, a city frequently receives just a dime or two of revenue for each dollar of liability. The engineering profession will argue, as ASCE does, that we're simply not making the investments necessary to maintain this infrastructure. This is nonsense. We've simply built in a way that is not financially productive.
We've done this because, as with any Ponzi scheme, new growth provides the illusion of prosperity. In the near term, revenue grows, while the corresponding maintenance obligations — which are not counted on the public balance sheet — are a generation away.
