Business Leaders Launch “Operation Boomerang” to Combat NYC Exodus Amid Mamdani Tax Policies

New York’s political and financial leaders have mobilized to counter what they describe as a growing exodus of wealthy businesses and individuals from the city, triggered by Mayor Zohran Mamdani’s progressive tax policies.

The conflict escalated after Mamdani specifically named Citadel LLC CEO Ken Griffin in an advertisement promoting a new tax on luxury second homes. Griffin publicly characterized the mayor’s approach as “creepy,” and his company subsequently indicated it might abandon plans for a $6 billion renovation of a new Midtown Manhattan office skyscraper.

“What the mayor of New York has made clear to my partners… is that we need to double down on our bet in Miami,” Griffin stated during the Milken Institute Global Conference on Tuesday. He emphasized his preference for operating in states that “embrace business, education, personal freedom and liberty.”

In response to the potential loss of major business investments, Andrew Murstein, founder of Medallion Financial Corp., has launched “Operation Boomerang,” committing $1 million of his personal funds to lure departed businesses back to New York. The campaign will send New York staples like hot dogs, bagels, and Katz’s Deli items to businesses that relocated to Florida.

“The last 10 years with mayors and governors, those things pass, and they should be in it for the long run,” Murstein told the New York Post. “I’m trying to convince them not to abandon ship. Whatever it takes.” He plans to leverage his initial contribution into a larger campaign, hoping to raise between $20 million and $30 million.

Former Mayor Eric Adams has also joined the effort, publicly urging Griffin to “stand your ground” in a post on social media platform X. The intervention by Adams highlights the growing concern among the city’s establishment about the potential economic impact of Mamdani’s policies.

The tax dispute represents more than just a conflict between a mayor and business leaders—it reflects broader tensions over New York City’s economic future. New York has historically relied on tax revenue from high-income residents and businesses to fund public services. Industry analysts note that the city’s top 1% of earners contribute nearly 50% of personal income tax revenue.

Reports suggest Mamdani’s own staff members are concerned about the mayor’s approach to business relations. According to anonymous sources quoted by the New York Post, “The mayor’s office is feeling pressure around this, and they are looking for ways to change the narrative around business.”

“They’re in a pickle because he’s hearing all the business leaders are looking for exit strategies now and Mamdani needs money and needs to keep his base happy,” one source reportedly said.

The Griffin situation mirrors similar conflicts in other cities where wealthy individuals have relocated operations after tax policy changes. In 2022, Griffin moved Citadel’s headquarters from Chicago to Miami, citing concerns about crime and tax policies in Illinois.

Economic development experts point out that major financial institutions like Citadel bring not just direct jobs but also support an ecosystem of related businesses, from law firms to restaurants. A departure of such firms could have multiplier effects on the local economy.

“This might be an inflection point because NYC is already a welfare state supported by very few people at the top who can leave,” one source told the Post, highlighting concerns about the city’s tax base stability.

As the standoff continues, the outcome may signal whether New York City can maintain its status as a global financial center while pursuing progressive tax policies, or whether it will experience a significant realignment of its economic landscape.
