The argument turns a century-old tax fight into a modern warning about wealthy residents, city budgets and political promises. The sharper question is whether New York can raise revenue and protect affordability without pushing away the people and capital it depends on.
Zohran Mamdani, Cleveland and New York City are linked in a new political cautionary tale: Cleveland’s past urban-policy failure is a warning for New York City, and the Cleveland example is used to criticize his approach to governing New York City. The argument, published in a New York Post opinion essay under the “Mamdani beware” frame, revives “Cleveland’s forgotten folly” — a 1910s tax fight involving John D. Rockefeller — to say cities can lose wealth, institutions and influence when they signal hostility to mobile capital.
The point is not just tax rates. It is how leaders balance populist demands for relief with the long-term value of people, businesses and donors who can leave.
The Rockefeller dispute at the center
The Post essay, written by Bob Sloan, reaches back to Cleveland’s dispute with Rockefeller to make its warning. Rockefeller had deep Ohio ties: Standard Oil was originally incorporated in Cleveland, and his family maintained Forest Hill, an estate in East Cleveland.
By the late 19th century, though, Standard Oil’s corporate life was already becoming more mobile. The company moved its headquarters to 26 Broadway in New York in 1885, according to Sloan’s account, and later reincorporated as a New Jersey holding company in 1899 after New Jersey made its corporate laws more attractive.
The Cleveland break came later. Sloan writes that after Rockefeller stayed through the winter while his wife was ill, Cuyahoga County tax commissioners John Flackner and William Agnew treated him as a local resident for tax purposes and sent him a $1.5 million bill, described in the essay as roughly $200 million today. They also threatened a 50% penalty for nonpayment.
According to the Post piece, officials publicized the bill and suggested ordinary residents could benefit from a 20% tax cut if Rockefeller paid. Rockefeller did not pay, left Forest Hill and never returned, Sloan writes. The promised local windfall, the essay argues, never arrived.
Why Mamdani is the target
The comparison is aimed at Mamdani because the essay casts him as part of a long political tradition: leaders who promise relief to working and middle-class residents by extracting more from wealthy people, property owners and business elites.
Sloan points to current debates in New York City over taxation, regulation and housing. He frames measures such as mansion taxes, pied-à-terre surcharges and rent freezes not merely as separate policies, but as a broader signal about the city’s relationship with capital.
That is the heart of the critique. A city may see a tax proposal as a fair way to fund services or ease pressure on residents. Investors and high-income taxpayers may read the same package as evidence that the political climate has changed — and that other cities are safer places to build, buy, donate or relocate.
Supporters of more aggressive taxes and tenant protections would push back hard. They argue that New York’s affordability crisis is real, that wealth concentration has grown extreme, and that public services require money. To them, asking those with the greatest ability to pay is not punishment; it is basic civic responsibility.
The signal matters more than one bill
The most useful part of the Cleveland analogy is not the idea that one tax bill can ruin a city. It is the idea that cities compete through signals.
In Sloan’s telling, New Jersey did not accidentally benefit from Standard Oil’s reincorporation. It changed its rules to attract business. The essay makes a similar point about today’s Austin, Nashville and Miami, which have marketed themselves as lower-friction alternatives for talent, companies and capital.
New York has advantages those cities cannot easily copy: global finance, culture, universities, transit density, immigration networks, media, hospitals and a massive labor market. But those advantages are not a force field. They can be weakened if residents or businesses come to believe the cost of staying is rising faster than the benefit.
That is why the Rockefeller story keeps resurfacing in arguments about urban governance. It turns a budget fight into a question of compounding returns: what a city gains from a short-term political win versus what it may lose over decades if money, institutions and ambition go elsewhere.
Where the analogy gets shaky
The cautionary tale is powerful, but it is not airtight. Rockefeller’s business and personal ties were already spread across multiple states before the Cleveland tax dispute. Standard Oil had moved its headquarters to New York decades earlier, and its New Jersey reincorporation reflected corporate law competition, not simply Ohio taxation.
It is also difficult to prove that Cleveland lost a specific century of philanthropy because of one confrontation. New York became the home of Rockefeller University, the Rockefeller Foundation, Rockefeller Center and other major institutions. But urban rise and decline are shaped by many forces: industry, migration, transportation, finance, race, governance and federal policy, not only the choices of one wealthy family.
There is another limitation. Cities cannot govern solely to please their richest residents. If the fear of departure blocks every tax increase, housing regulation or worker protection, then the people who cannot leave bear more of the burden. That, too, can damage a city’s future.
The real policy challenge is calibration. A tax or housing rule can be justified on fairness grounds and still be poorly designed. A pro-business posture can help a city grow and still leave renters, workers and low-income residents behind.
What New York should watch
For New York City, the practical question is not whether rich people dislike taxes. Many do. The better question is whether policy choices change behavior at the margin: where founders incorporate, where executives live, where donors build institutions, where landlords invest, and where mobile residents decide to spend most of their year.
The warning signs would not appear all at once. They would show up in tax-base concentration, business formation, office demand, housing construction, high-income migration, philanthropic commitments and the tone of private-sector expansion plans. A city can look stable while decisions that shape the next decade are already being made.
Mamdani’s critics see Cleveland as a flashing red light: do not turn wealthy residents and investors into political villains, because they may take their future contributions elsewhere. His defenders can answer that New York’s crisis of affordability also carries long-term costs, and that a city hollowed out by unaffordable housing is not healthy either.
That is why the Cleveland example is best understood as a warning, not a verdict. It does not prove that New York must reject higher taxes or stronger housing protections. It does show that city policy is read not only by voters, but by people and institutions deciding whether New York still feels like a place to commit for the long run.
