Within the first half of this sequence, we appeared on the historical past of the infamously car-centric American suburb, and the second evaluated their desirability. On this remaining half, we’ll flip to their fiscal impression and the query of sustainability.
Are the suburbs merely the much less dense outskirts of a metropolis, or are they—as their detractors wish to say—a Ponzi scheme that’s swamping states and native municipalities with unrepayable debt whereas leeching off the cities that subsidize them?
Backed by the Cities?
The advocacy group Sturdy Cities is without doubt one of the most ardent supporters of city densification and highlights the city of Lafayette, Louisiana, to make its case that cities unfairly subsidize their suburbs. As they describe it:
“Like most cities, Lafayette had the written stories detailing an enormously massive backlog of infrastructure upkeep. At present spending charges, roads have been going unhealthy quicker than they may very well be repaired. With aggressive tax will increase, the fee of failure may very well be slowed, however not reversed. The story underground was even worse. That didn’t make sense to Kevin or to town’s mayor, a man named Joey Durel.
Joe, Josh, and I interviewed all town’s division heads and key workers. We gathered as a lot knowledge as we may (they’d lots). We analyzed and then mapped out all of town’s income streams by parcel. We then did the identical for the entire metropolis’s bills. This was essentially the most complete geographic evaluation of a metropolis’s funds that I’ve ever seen accomplished. Once we completed, we had a three-dimensional map displaying what components of town generated extra income than expense.”
This is the map they got here up with:

Inexperienced areas herald cash, and purple are a web expense. The peak of the road reveals how a lot of a web earnings/expense these areas are.
The article continues:
“The largest drawback that jumped out was that the substitute value of town’s infrastructure was $32 billion, whereas the whole inhabitants’s wealth added to solely $16 billion! They estimated that the median family would must pay a minimum of $3,300 a yr and as a lot as $8,000 in taxes simply to keep up the infrastructure versus the roughly $150 they have been paying.”
We’ll get to the price range shortfalls quickly sufficient. For now, as you’ll be able to see, the denser city areas herald cash, whereas the outlying, much less dense (i.e., extra suburban) areas value cash.
Nonetheless, this evaluation is clearly skewed, because the downtown space seems like inexperienced skyscrapers. Downtowns are sometimes business hubs, each by way of work and retail. They might be web boons even when nobody lived there in any respect, as many individuals from the suburbs and exurbs journey there to work and store. Merely densifying the outlying areas wouldn’t change this.
One other evaluation from the Canadian city of Halifax gives what I feel is a greater (and positively much less dramatic) image. It discovered that the typical annual value to town for an city family was $1,416, in comparison with $3,462 for a suburban family.

The very first thing to notice is that the numbers supplied by Halifax don’t sq. with the scenario in Lafayette in any respect. Certainly, the price of all infrastructure (roads, sidewalks, curbs, water traces, and sewer traces) amounted to $1,284 for suburban properties—not even near the $8,000 Lafayette supposedly wanted. I think the Halifax numbers are extra consultant. In spite of everything, our cities have been sprawled for some time now and haven’t fully collapsed.
We also needs to be very cautious about claims about who’s subsidizing whom. For instance, the Brookings Institute notes, “At this time, practically 60% of all welfare instances might be present in 89 massive city counties,” whereas TIFs (Tax Increment Financing, a technique of subsidizing actual property growth) is, because the U.S. Division of Transportation states, “extra frequent in city areas than in rural areas.”
Different company tax incentives are usually for developments in city areas as effectively. For instance, the Division of Transportation additionally notes that of Certified Alternative Zones (one other tax profit for growth), “38% are in city tracts, and 22% are in suburban tracts.”
Rural areas have essentially the most Alternative Zones, however this is nonetheless deceiving. In spite of everything, in 2018, there have been about 151 million individuals in America’s suburbs and exurbs and solely 25 million within the city cores, which makes the distinction per capita within the variety of alternative zones for city areas versus the suburbs over 10 to 1.
In Kansas Metropolis, the place I dwell, town just lately put in a streetcar that (will ultimately) go from downtown Kansas Metropolis to the favored Plaza space. In different phrases, it should go from the densest a part of the whole metro space to the second-densest a part of the metro space. The undertaking obtained a $20 million federal grant in August 2013 and is in search of $174 million extra in federal cash to finish.
In different phrases, on this case, the suburbs are subsidizing town.
And this is true with nearly all public transit apart from buses. In 2018, authorities spending on public transit was $54.3 billion. Talking of getting old infrastructure, it had an over $100 billion upkeep backlog.
However that doesn’t change what appears to be a well-documented reality: Suburban infrastructure is costlier to keep up than city. The spotlight of this inefficient use of land and the compelled subsidization of the suburbs (and rural cities, for that matter) is the city of Backus, Minnesota. As the favored anti-suburb YouTuber Not Simply Bikes notes:
“An excessive case is the small city of Backus, Minnesota, which was on the finish of lifetime of its wastewater system. However as a result of this city was made up of sprawling, low-productivity, car-centric infrastructure, the wastewater system was sprawling and wasteful as effectively. The substitute value was $27,000 per household, which was the median family earnings of the city.”
Not Simply Bikes notes that such cities ought to have septic programs and wells, not a “sprawling wastewater system.” And it’s laborious to argue with that logic. He’s proper right here.
Certainly, the case for such a prudence, in addition to rising density the place doable and viable, is pretty robust. Clearly, densifying rural farming cities would defeat the aim of farming, however for essentially the most half, infill is superior to additional sprawl. However the case being made is usually overstated or even wildly overstated, whereas the issues inflicting flight to the suburbs (just like the crime difficulty mentioned in Half 2 of this sequence) get ignored.
There’s additionally a bizarre city bias at play. For instance, one other in style anti-suburb YouTuber named Alan Fisher has a video with the textual content on the thumbnail studying “I Don’t Care In regards to the $$$” on the subject of one of many largest boondoggles in American infrastructure historical past, specifically, California’s high-speed rail undertaking to attach San Francisco and Los Angeles.
Again in 2008, this undertaking was initially envisioned to value $40 billion in whole and be completed by 2020. Effectively, it’s 2024, the undertaking is now anticipated to go a cool $100 billion over price range (hopefully, this makes you are feeling a bit higher about your final rehab undertaking), and there actually is not any finish in sight.
So, if we’re going to wag our finger at Backus, Minnesota, what ought to we make of this farce of a undertaking? And why ought to taxpayers—each city and suburban alike—be subsidizing it?
A Ponzi Scheme?
Regardless of my criticisms of city activists, the proof they supply does point out suburban infrastructure is notably costlier to keep up than city infrastructure. Thereby, we needs to be trying to construct denser when doable, even in outlying areas. This would additionally assist alleviate among the “soullessness” I complained about in Half 2 relating to business facilities in suburban areas.
However once more, the anti-suburb people take their arguments means too far. In actual fact, this time, they go overboard, claiming “the suburbs are a Ponzi scheme.” Charles Marohn with Sturdy Cities explains that the primary strategies of progress profit a metropolis instantly “from all of the allow charges, utility fees, and elevated tax assortment… [but] Cities additionally assume the long-term legal responsibility for servicing and sustaining all the brand new infrastructure, a promise that received’t come absolutely due for many years.” The second half is the issue, as “the income collected over time doesn’t come close to to protecting the prices of assembly these long-term obligations.”
This is the “progress Ponzi scheme” the car-centric suburbs have created, or extra precisely, are the product of. To ensure that a metropolis to remain solvent with this mannequin, they should proceed to develop till, like with Bernie Madoff and all Ponzi schemes, you’ll be able to’t get sufficient progress to finance the prices of the prevailing infrastructure, and all of it comes crumbling down.
Marohn concludes that:
“To financially maintain itself, then, a metropolis or city using the American suburban growth sample and making this tradeoff should imagine one of many following two assumptions to be true:
1. The quantity of monetary return generated by the brand new progress exceeds the long-term upkeep and substitute value of infrastructure the general public is now obligated to keep up, OR
2. The town will all the time develop in ever-accelerating quantities in order to generate the money stream essential to cowl long-term obligations.”
For the reason that monetary return generated by new progress with suburbs doesn’t exceed long-term upkeep prices, for a metropolis to be financially possible, it should develop eternally to remain financially viable; thus, it’s a Ponzi scheme.
This is, nevertheless, the actual similar mistake that some libertarians make when describing Social Safety as a Ponzi scheme. Sure, like a Ponzi scheme, Social Safety takes cash from traders (or taxpayers, on this case) and pays out their principal to different traders (on this case, retirees). However that’s not sufficient to make for an excellent analogy. In spite of everything, a lot of your intestine flora and the bubonic plague are each micro organism, so ought to we assume they’re the identical?
A Ponzi scheme is inherently a closed system. The principal from new traders is used to pay the returns of earlier traders. Not solely that, however the returns must be excessive sufficient to elicit new “funding.” With Social Safety, the returns might be diminished to ranges under that which the taxpayer put in (and so they have been to admittedly paltry ranges).
Infrastructure doesn’t want excessive returns; it simply must be maintained. Furthermore, American infrastructure, like Social Safety, is just not a closed system. Tax cash might be raised from different sectors of the economic system to fund it, as has been finished to the chagrin of many city advocates.
Marohn admits this a lot himself in one other piece, the place he notes there are 4 methods American cities finance progress:
- Authorities switch funds
- Transportation spending
- Debt
- The expansion Ponzi scheme
The primary two of those could not be best, however they’re sustainable.
The state of U.S. infrastructure is kind of unhealthy total. Each the Trump and Biden administrations made infrastructure enchancment a key plank of their platform, for good motive. In 2021, the American Society of Civil Engineers launched a report concluding that, amongst different issues, 43% of U.S. roadways are in poor or mediocre situation, and america faces a $2.59 trillion shortfall in infrastructure wants over the subsequent 10 years.
Whereas this sounds daunting, that quantities to a “mere” $259 billion per yr. In 2024, america GDP is over $28 trillion, and the federal government spent an obscene $916 billion per yr on “protection,” greater than the subsequent prime 10 international locations mixed.
I feel we may nonetheless defend our nation quite simply by chopping that in half. That will pay for all of the infrastructure wants with out ending the suburbs and nonetheless have sufficient left over to scale back the deficit or minimize taxes in addition.
The entire “Ponzi scheme” argument may make for a pleasant sound chunk, however it’s not true and doesn’t assist their case. Due to this fact, the suburbs aren’t a Ponzi scheme.
Unpayable Debt?
As a substitute of paying as they go, have American cities relied as a substitute on mountains of debt to keep up their overly sprawled infrastructure every time it requires an overhaul? As Not Simply Bikes places it:
“The town could get it constructed for reasonable, however the metropolis is in the end accountable for sustaining that infrastructure eternally. The massive drawback begins if there isn’t sufficient tax income collected to cowl the substitute value of the infrastructure…once you get a few generations into the suburban experiment, the upkeep obligations of the previous begin to meet up with you.”
So what do our cities do? They tackle debt.
In one other video, Not Simply Bikes gives this chart to point out that public sector indebtedness is extremely correlated to overhauling our infrastructure after every life cycle, which is closely correlated with the nation’s indebtedness.

The argument makes logical sense however doesn’t appear to be backed up by the chart he gives, which reveals debt rising at about the identical tempo after which nearly doing the alternative of what anti-suburb activists say it ought to in 2000 when the “second suburban life cycle” completed.
Not Simply Bikes then provides non-public indebtedness to the image, and it’s ugly. However shouldn’t failing public infrastructure primarily have an effect on public debt, not non-public?

Moreover, if we take a look at what the U.S. authorities spends its cash on on the native, state, and federal ranges, infrastructure is a comparatively small piece of the puzzle.

Infrastructure would fall beneath “different,” making it considerably lower than 16% of public sector spending. In 2017, for instance, all ranges of presidency spent $5.6 trillion in whole and $309.2 billion on infrastructure and transportation. So 5.48%, to be actual.
Moreover, whereas municipal debt has grown to a whopping $4.1 trillion in 2022, it has leveled off during the last decade, and as a share of GDP, it has fallen from nearly 27% in 2012 to a bit over 16% at present.

Remaining Ideas
It could appear that I have been fairly important of the pro-urban, anti-suburb activists all through this three-part sequence. And certainly, a lot of their claims, from the streetcar conspiracy to the suburban Ponzi scheme, don’t maintain water.
Certainly, even evaluating American suburbs to European ones is a little bit of a purple herring. The stereotype of dense, city European cities with unbelievable public transportation applies predominantly to its massive cities. There are loads of suburbs in Europe that look quite American, as yow will discover from any fast Google search.
However there are some good factors buried inside. Suburban growth prices extra to keep up than city growth, and it thereby is sensible to construct denser when doable. Moreover, the business facilities in suburbia are boring, car-dependent monstrosities. Walkable malls appear to have died, however making extra walkable “vacation spot factors” quite than limitless rows of strip malls could be a marked enchancment.
Single-use zoning also needs to be finished away with in business areas and (a minimum of principally) changed with multi-use zoning, which provides vibrancy and prevents business zones from going useless and turning into crime magnets at evening.
However city advocates not solely exaggerate (generally wildly) their claims—in addition they have vital blind spots. The obvious is crime. As a substitute, they have an inclination to deal with extra coercive strategies of stopping suburban sprawl than creating incentives for individuals to remain in and transfer to city areas (like decreasing crime). We see this course of in issues like city progress boundaries, which typically trigger actual property costs to extend dramatically and worth out the center class.
Higher options would embody incentives to infill versus constructing new subdivisions. Latest strikes towards permitting property homeowners to construct ADUs (accent dwelling models) in numerous cities is an excellent begin.
General, suburbia was created predominantly by what the automobile allowed individuals to do, not by conspiracies amongst automobile producers. And the suburbs haven’t been a catastrophe, though it comes with important downsides.
It’s commonplace for the outlying areas of cities to be considerably much less dense than the city core. Whereas it is sensible to maneuver towards extra densification total, it doesn’t make sense to desert the suburbs, pack individuals into pods in dense cities like sardines, or attempt to part out the car with numerous coercive strategies.
