JPMorgan Chase CEO Jamie Dimon has opened up about his recent private meeting with the Mayor of New York City Zohran MamdaniHe said he warned socialists about the risks of bad governance and ideology-driven policy making.Speaking to Fox Business Network host Maria Bartiromo on Friday, Dimon called the closed-door meeting “pleasant” but made clear he did not back down during the conversation.Dimon said, “He was very polite. It was very serious. We had a very good conversation, but I said everything I wanted to say.”The banker said she used the debate to speak out on key issues affecting New Yorkers, including affordable housing and child care. However, he said poorly designed policies could create bigger problems rather than solutions.“I have to talk about affordable housing and child care. Most people want it. If you do it badly, it will be a disaster… Do it right. There are studies that can tell you how to do it right. Get people involved who know what they’re doing and implement appropriate policies,” he said.Dimon also criticized politicians who focus primarily on taxes and spending rather than fixing the system and administration.“Good policy is free,” he said. “I want to say to politicians, ‘Don’t try to raise more taxes or spend more money, sit down and decide policy.’The JPMorgan boss also pointed to Mamdani’s lack of executive experience while discussing the challenges of running America’s largest city.“I mean, he’s now running a city with 300,000 employees,” Dimon said before the Reagan National Economic Forum in California.“And I’ve seen mayors fail miserably because they can’t make themselves run out of a paper bag, or ideology blinds them from practical, realistic, real-world policy. And so we’ll see.”He said he would be willing to help if the administration adopts practical solutions.“And, you know, if I can help them do good things, I’m happy to do that.”The meeting took place on May 18, when Mamdani met separately with both Dimon and Goldman Sachs Chief Executive David Solomon. The talks came amid growing concern from business leaders over Mamdani’s proposed economic policies, which also include a tax on second homes worth more than $1 million. The mayor recently faced criticism after filming a promotional video for the proposed tax outside a penthouse owned by hedge fund billionaire Ken Griffin.Griffin later described the move as “scary” and announced plans to further expand Citadel’s operations in Florida rather than New York. He also suggested the company might reconsider its planned $6 billion development project on Park Avenue.When asked about the controversy, Dimon suggested that Mamdani may regret the video.“My guess is he probably regrets it,” Dimon said.He added, “But you’ll have to ask them that.”
