I would take this with a huge grain of salt
- Other countries do have expansive suburbs. They don't look like ours, but they are fundamentally the same. Get outside of any major metropolitan and you will see spaced out houses in subdivisions with lawns.
- The ASCE number is a bit of a joke - this is a marketing number for the purposes of pushing investment in engineering firms. In reality, your city doesn't need to pay to rebuild every suburban road it has when filling potholes is cheap.
- Furthermore, this article does nothing to actually link these liabilities to where the revenues occur. The giant cost of replacing an aging power plant completely dwarfs the cost of suburban power lines. But a new subdivision is a huge tax boon to a community.
