A fresh push to tax the wealthy in New York City has ignited a fierce backlash, with prominent venture capitalist Kevin O'Leary leading the charge against the proposals. The 'Shark Tank' star did not mince words during an appearance on Fox Business, dismissing the plan as economically reckless and warning that it could drive high-net-worth individuals—and their money—out of the city entirely.
O'Leary's Scathing Critique
O'Leary launched a blistering attack on the tax proposals linked to New York City mayoral candidate Zohran Mamdani. 'Let me count how many ways this policy is stupid,' he said bluntly. He argued that New York needs more wealthy residents, not fewer, because they 'pay taxes, pay maintenance, create jobs—and don't use the city's services.' According to O'Leary, the city's economic vitality depends on retaining its affluent population.
The Proposed Tax Measures
At the center of the controversy are proposals aimed at increasing taxes on wealthy homeowners and investors. These include a so-called 'pied-à-terre' tax on second homes, which would impose an annual surcharge on all luxury residences valued at over $5 million that are used as secondary dwellings. The measure is projected to generate approximately $500 million annually, intended to help close the city's budget deficit.
Supporters argue that such taxes are necessary to plug budget gaps and fund public services, especially as cities grapple with rising costs. However, critics warn that targeting mobile wealth could backfire, particularly in an era when capital and people can relocate with ease.
Backlash from Business Leaders
O'Leary is not alone in his opposition. Ken Griffin's Citadel LLC recently announced it is reconsidering its planned redevelopment of 350 Park Avenue after Mamdani singled out the entrepreneur in a viral video promoting the new tax. Standing outside Griffin's $238 million penthouse at 220 Central Park South, Mamdani pointed to the luxury apartment and declared that the policy would specifically target high-value residences 'like this penthouse.'
Griffin broke the record for the most expensive home purchase in the US when he bought the Manhattan penthouse in 2019, though his primary residence is now in Miami, Florida, after relocating his hedge fund in 2022. The video drew sharp criticism from CNBC anchor Sara Eisen, who slammed Mamdani for 'demonizing' a private citizen. 'Ken Griffin employs thousands of people in NYC and is planning to build the tallest office tower on Park Ave., investing billions more and creating thousands more jobs,' she said in his defense.
Hedge fund manager Dan Loeb also condemned the video, calling it 'childish' and warning that it could damage jobs and tax revenue.
Broader Tensions Over Taxation
The debate reflects a broader tension playing out across major US cities: how to raise revenue without discouraging investment. In recent years, many high earners and businesses have relocated from high-tax states like New York and California to lower-tax regions such as Florida and Texas—a shift that has raised concerns about long-term tax bases.
Supporters of the proposed measures insist that the burden should fall on those most able to pay, particularly as inequality widens and cities face mounting fiscal pressure. But opponents argue that targeting mobile wealth is risky in an era where capital and people can move more easily than ever.
For now, the fight is far from over. If O'Leary's reaction is any indication, the battle over taxing the rich is only just heating up.
