When New York State Assemblymember Zohran Mamdani recently declared, “I don’t believe we should have billionaires,” he wasn’t indulging in empty populism, he was articulating a moral position whose time has come. The existence of billionaires, in an era defined by mass homelessness, food insecurity, and climate collapse, is not merely unfortunate, it is an ethical indictment of the systems that allowed them to exist in the first place.
Mamdani joins a growing chorus of progressive thinkers, economists, and ethicists who argue that no individual should have the right, or the capacity, to accumulate and hoard a billion dollars or more. This isn’t about envy or political expediency. It’s about the increasingly clear understanding that billionaire wealth isn’t just excessive, it’s extractive, destabilizing, and morally indefensible.
Billionaire Wealth Is Built on Exploitation
To amass a billion dollars, one must either inherit extreme wealth or systematically profit from the undervalued labour of others. Most billionaires, especially those in tech and finance, profit not through invention or hard work, but through ownership of capital, tax avoidance, and labor suppression. As economist Thomas Piketty demonstrated in Capital in the Twenty-First Century, returns on capital consistently outpace economic growth, meaning that wealth accumulates faster than wages rise, thus enriching the few while immiserating the many (Piketty, 2014).

This is not a bug in capitalism; it’s a feature. While billionaires build personal rockets and collect rare yachts, tens of millions lack clean water, reliable housing, or access to medical care. The wealthiest 1% of the global population now owns nearly half of the world’s wealth, while the bottom 50% hold just 2% (Credit Suisse Global Wealth Report, 2022).
Morality Demands Redistribution, Not Charity
Some argue that billionaires are philanthropists who “give back.” But ethical redistribution is not about generosity, it’s about justice. Charity, even when well-intentioned, is discretionary. It allows the wealthy to decide which causes are “worthy,” often with tax write-offs and public accolades. It is fundamentally undemocratic.
As philosopher Peter Singer wrote in his essay Famine, Affluence, and Morality, if we can prevent something bad from happening without sacrificing anything of comparable moral importance, we are morally obligated to do so (Singer, 1972). Billionaires could eradicate global hunger, fund universal education, and fight climate change many times over. That they do not is a moral failure, one built into the very logic of their class interests.
The Billionaire Class Undermines Democracy
More than just a matter of inequality, billionaires represent a profound threat to democracy. They use their wealth to shape elections, control media narratives, lobby governments, and suppress movements that challenge their power. As Mamdani put it, they spend “millions of dollars” to influence outcomes that serve their continued dominance. That’s not civic participation, it’s oligarchy.
This is evident in the staggering political spending from figures like Elon Musk, Jeff Bezos, and the Koch brothers, whose influence often counters popular will on issues like climate regulation, taxation, and labor rights. When money becomes speech, those with the most money speak loudest, and everyone else is drowned out.
Making Billionaires Illegal Is Not Extremism – It’s Ethics
To say that billionaires should be “illegal” is not to suggest rounding them up and seizing their mansions. It means creating systems in which it is structurally impossible to accumulate wealth beyond a certain point. This might include steeply progressive taxation, strict inheritance limits, and aggressive corporate regulation. As proposed by economists like Gabriel Zucman and Emmanuel Saez, a global wealth tax would not only generate trillions in public funds, but also dismantle the foundations of permanent wealth aristocracy (Zucman & Saez, 2019).
When Mamdani says billionaires “shouldn’t exist,” he invites us to imagine a society where wealth is shared, not hoarded; where innovation is public, not privatized; and where dignity isn’t auctioned to the highest bidder. This vision isn’t utopian, it’s already partly realized in countries with higher levels of equality and lower poverty rates, such as Norway, Denmark, and the Netherlands.
A Future Without Billionaires Is a Future With Hope
We are standing at a crossroads: ecological collapse looms, fascism festers, and inequality grows by the hour. Allowing the existence of billionaires in this context is more than complacent, it’s complicit. As the climate crisis worsens and democratic institutions strain under the weight of elite influence, we must ask: how much longer can we afford billionaires?
The answer, increasingly, is: not one more day.
