Suburbs have existed for more than 100 years, start with thee streetcar suburbs (which often feature lots larger than what the new suburbs around me are building). They have already added sewer, water, telephone, eclectic, cable TV, internet, and some of those have been replaced as well. They have already replaced their roads many times over the years.
Sure there are some suburbs that have been badly managed and so haven't kept up. However that is a reflection on the short sighted voters, and not suburbs.
Then I took that overall very positive lens and started to apply it to what I saw and the financial arguments didn’t hold up to what I could plainly see in the low-density, car-dominated towns and suburbs around me.
They suggest it takes almost 30 years for the maintenance burden to actually have a fiscal impact.
From my understanding Strong Towns think "lower density, less intensely urban development" towns are fine. E.g. at 0:57 of the video, it's anything but intensely urban development.
"In this example, a 100-year-old commercial block, built in the traditional style of development, drastically outperformed a shiny new development, created in the modern car-centric style."
But then I look at the housing prices. TimPC's explanation seems legit.
I would really only categorize Lincoln and Wellesley "low density suburb". The rest certainly have car centric qualities but they're too built up to be called the exception to the rule.
