“It’s impossible to earn a billion dollars.” That was how Mark Bou Mansour of the Tax Justice Network framed it, and in New York City the world capital of billionaires this is more than a motto. It’s the rallying cry of 33-year-old democratic socialist Zohran Mamdani, who recently won the Democratic mayoral nomination. In a town where there are 123 billionaires worth a combined $759 billion, Mamdani’s campaign is as much about changing fortunes as it is about getting elected.
Mamdani’s platform is an indictment of the establishment. I don’t think that we should have billionaires because, frankly, it is so much money in a moment of such inequality, he said in an interview with NBC News. His ideal: A city in which every single individual can succeed, not only the penthouse and private helipad owners. And he’s not shy about the label: I’m fighting for the very working people that ran a campaign to empower that he has since then betrayed, Mamdani fired back after being called a “communist lunatic” by the former president.
But is Mamdani really as radical as his critics claim? As Stanford international studies professor Anna Grzymala-Busse observed, “Mamdani is NOT a communist.” Rather, his ideas rent controls, state-owned supermarkets, free public transit, universal childcare are all about making the basics accessible and affordable. As Ted Henken from Baruch College points out, “The New Yorkers who support him seem to do so not because of any communist ideology on his or their part, but because he proposes to address this crisis of affordability.”
Let’s break down what Mamdani’s “Zohranomics” could mean for New Yorkers. First, a rent freeze on about a million rent-stabilized units, along with a ambitious plan to build 200,000 additional units of affordable housing over the next ten years. Economist Isabella Weber, who endorsed Mamdani’s campaign, says this approach is about “unleashing the public sector to build housing for the many.” And it’s not just talk: Mamdani wants to double the city’s investment in public housing and use NYCHA-owned land for new developments a nod to the city’s most successful affordable housing expansions from decades past.
Food deserts? Mamdani’s solution is a chain of city-run grocery stores, one in each borough, to introduce healthy, cheap food into the very communities that are most in need. “If you have an alternative that is reliably cheap and doesn’t take advantage of opportunities to raise prices when they occur, that can change the pricing dynamic for whole sectors,” Weber said in her interview.
And then there is the expensive ticket: universal, free early care for all New Yorkers 6 weeks through 5 years. This is not fantasy France, Sweden, and Germany show through studies that universal child care keeps urban families put and benefits kids and parents both.
How does Mamdani fund it all? By increasing the city income-tax rate on billionaires and increasing the state corporate tax. Critics, such as former governor Andrew Cuomo, caution that this will trigger a billionaireodus. But analysis in recent studies indicates the specter of tax flight is overstated after all, a Manhattan address remains the ultimate status symbol.
The battle over taxing the ultrarich isn’t just local. Internationally, the struggle is also escalating. Over a dozen billionaires like Abigail Disney and George Soros have publicly asked to be taxed more, contending, “America has a moral, ethical and economic responsibility to tax our wealth more,” as suggested in their open letter to presidential candidates. And. It’s not only the U.S. a recent Tax Justice Network report estimated that nations would collect $2.1 trillion annually if they implemented a “featherlight” wealth tax model based on Spain’s system, with very little billionaire flight.
But it’s not all who are so confident. Detractors cite European examples where wealth taxes were repealed for ineffectiveness at generating revenue and administrative expense. But the data aren’t quite so black and white: Switzerland’s wealth tax, for instance, regularly raises more than 1% of GDP, and research indicates that fewer than 0.01% of Norway, Sweden, and Denmark’s very richest households moved following wealth tax reforms.
Beyond the numbers, there’s an even larger question: what happens to democracy when there’s such profound wealth? As Europeans and Brookings researchers have discovered, the billionaire boom is driving inequality and eroding the very foundations of democratic society. When a few own this much, it’s not only about dollars it’s about power, influence, and who gets to shape the future.
Mamdani’s campaign is more than a policy wishlist. It’s a challenge to the idea that billionaires are a natural part of city life. As Martin Luther King Jr. once said, “Call it democracy, or call it democratic socialism, but there must be a better distribution of wealth within this country for all God’s children.” In the city with the world’s biggest billionaire gap, that message is resonating louder than ever.
