While the article indeed barely touched on its headline, the way I've seen the "suburb infrastructure upkeep problem" described seems indeed reminiscent of a ponzi scheme.
The way I understand it:
Suburbs have a relatively low initial cost (for the city) compared to the taxes they generate. However, their maintenance cost is relatively high because Suburbs are huge.
Thus, US cities have long had a policy of paying the rising cost of their older Suburbs by creating new Suburbs - which is pretty analogous to a Ponzi scheme.
I think you misunderstand what a ponzi scheme actually is. It's a type of "investment" that's actually a scam where new investments are used to pay out older investors until the funds run out. It is named after the guy is famous for being the first to run one, Charles Ponzi.
In large chunks of this country the suburbs are comprised of hoas that bear a good chunk of the maintenance cost. And I would like to see actual proof that a suburb road needs more maintenance with passenger vehicles than a downtown road with large 3+ axle vehicles on it all of the time. If those roads do need more maintenance then that is likely a quality control problem that happens when you hire the lowest bidder for a job.
Don't feel bad. You are one of the hundreds if not thousands that I have interacted with that don't actually understand what a ponzi is and isn't. Not everything that doesn't work out or work out for everyone is a scam or a ponzi.
Oh and I did just skim the "article" and nothing it says leads me to the conclusion that ponzi is the right word here.
I'm not sure at the moment what the right term would be for what they are trying to describe but it's most definitely not ponzi.
