Initial infrastructure is often paid for with up-front cash transfers from the federal/state government and long-term loans, then the long-term maintenance is supposed to be funded by local taxes but in many cases is set up to be more expensive than the long-term available tax base, so infrastructure just starts falling apart and then either taxes go up or maintenance is put off and people left holding the bag are screwed, or external cash bailouts make up the difference.
In either case, the suburbanites (especially near the beginning of the construction cycle) and initial construction companies are getting a huge subsidy from everyone else (and from future generations) to promote an inherently unsustainable and destructive living arrangement.
It's a kind of Ponzi scheme, and like any other Ponzi scheme, at some point the music stops and then the whole system is in an extremely precarious place.
