The Globe and Mail reports in its Friday edition that New York Mayor Zohran Mamdani's campaign promise to raise taxes on the wealthy has led him to target Citadel founder Ken Griffin with a proposed tax on non-primary residences worth over $5-million (U.S.). The Globe's Gus Carlson writes that Citadel noted that while Mr. Griffin resides in Miami, the billionaire significantly supports New York, including a $6-billion redevelopment project in Manhattan that will generate over 20,000 jobs. Citadel hinted that the mayor's comments might prompt Mr. Griffin to pull out of the redevelopment project, killing the jobs. Why did Mr. Mamdani choose Mr. Griffin as the face of his tax-the-rich campaign? Perhaps his staff failed to research Mr. Griffin, or more likely, Mr. Mamdani's ideological ambitions overshadowed the economic consequences of his actions, suggests Mr. Carlson. He says the city's economy can't afford the mayor's antics. New York has been bleeding wealthy individuals, companies and jobs for some time. JPMorgan's Jamie Dimon has said repeatedly the situation has become so acute that companies face hard decisions about staying in New York. He said his firm now has more employees in Texas than in New York.
