President Donald Trump blasted New York City Mayor Zohran Mamdani’s proposed tax on second homes, warning the plan will drive residents out and “destroy” the city, while the mayor and state officials argue the measure targets the wealthy to close a growing budget gap.
“Sadly, Mayor Mamdani is DESTROYING New York! It has no chance! The United States of America should not contribute to its failure,” Trump wrote Thursday on Truth Social, taking direct aim at the Democratic mayor’s latest policy proposal.
“It will only get WORSE. The TAX, TAX, TAX Policies are SO WRONG,” he added. “People are fleeing. They must change their ways, AND FAST. History has proven, THIS ‘STUFF’ JUST DOESN’T WORK.”
The proposal at the center of the dispute would apply to second homes in New York City valued at more than $5 million, a plan unveiled jointly by Mamdani and New York Gov. Kathy Hochul.

State officials say the measure could generate roughly $500 million in revenue for the city, part of a broader effort to stabilize finances as New York faces a projected $5.4 billion deficit in the coming fiscal year.
“If you can afford a $5 million second home that sits empty most of the year, you can afford to contribute like every other New Yorker,” Hochul said in a statement outlining the policy.
Mamdani tied the proposal directly to the city’s fiscal challenges, framing it as a targeted approach that places the burden on wealthier property owners rather than working residents.

“Alongside the governor, our administration is fighting every day to make sure we address this fiscal deficit fairly, where the wealthy contribute what they owe and our budget reflects our commitment to the working New Yorkers being priced out of our city,” he said.
The clash over taxes quickly expanded into a broader debate about the mayor’s political platform, including questions about whether his brand of democratic socialism can extend beyond New York City.
During an interview on CBS, Mamdani was pressed on whether his policy approach could succeed in statewide or national elections, particularly in regions where the label “socialist” faces resistance.
“I will be honest with you, before I was the mayor I was an assembly member of Astoria in Long Island City. At that time, I was told you can only be a democratic socialist in northwest Queens,” Mamdani said.
“Then I became the mayor. Now the next question is the state, and then the next question will be, the country.”
“I think that this is a politics that can flourish anywhere because, frankly, there’s only one majority in this country and that’s the working class,” he added.
“And it’s time we have a politics that puts them at the heart of what we’re pursuing and not as part of the appendix.”
The mayor’s argument centers on economic inclusion, with his administration pointing to initiatives such as universal childcare and local infrastructure efforts as examples of policies designed to resonate beyond New York.
Questions about Mamdani’s relationship with Trump have also surfaced alongside policy disagreements, particularly over foreign policy issues including the war in Iran.
“We’ve had a conversation about a number of issues and that includes our disagreements on foreign policy,” Mamdani said when asked by “CBS Mornings” co-host Gayle King whether the two had discussed Iran directly.
“I will keep the frequency and the nature of those conversations private, because that’s the premise of them.”
The tax proposal has also fueled debate over whether higher levies on wealthy residents could trigger an exodus from the city, a concern frequently raised by critics of similar policies.
Mamdani rejected that claim, pointing to past tax increases on high earners that did not lead to a drop in the city’s millionaire population.
“For all of the discussion of the imagined exodus that would take place were we to tax the wealthiest New Yorkers by the appropriate amount — I say imagined because before I was a mayor I was a state legislator, and I was part of an effort to increase taxes on millionaires at that time — we were told the same thing then — and what we find now is that we have more millionaires today than we did at that time even after having passed that tax,” he remarked.
While dismissing concerns about wealthy residents leaving, Mamdani pointed to a different trend he says is already reshaping the city.
New York lost roughly 200,000 Black residents between 2000 and 2020, a shift he described as evidence of a growing affordability crisis rather than a reaction to taxation.
“And so for all of that conversation about this imagined exodus, we have to reckon with the very real exodus that we are seeing in the city, an exodus of working-class people, an exodus of those who cannot afford to live here,” Mamdani noted.
Socialism, Communism whatever you would like to call, has never worked and never will work.
