Democratic mayoral nominee Zohran Mamdani is giving business leaders fair warning: He promised he’d tax them and wealthy New Yorkers if elected — and he means to keep that promise.

He basically dared them to leave the city if he did.

If that happens, say goodbye to city tax revenue and jobs and hello to a downward spiral.

On Tuesday, the Dem front-runner met with 100 of the city’s top business leaders and made absolutely no attempt to hide his plans.

“He didn’t back away from any policy position,” one attendee told The Post. 

As The Post’s Charles Gasparino reported, many top business honchos are “looking for an exit strategy rather than a strategy to deal with a Mayor Mamdani.”

Who can blame them?

The far-left Democrat is already on record saying that billionaires shouldn’t exist.

For years, Mamdani and his socialist pals have plotted to take power in “the center of US capitalism,” and now they’re on the verge of getting “a chance to flex [their] muscles.” 

The city’s bankers and business elite are understandably worried.

Mamdani is also looking to freeze or cut NYPD funding, destroy the housing market with a rent freeze and have government take over private businesses like supermarkets.

Plus he’s likely to bring a whole pack of lefty Democratic hacks and a passel of Democratic socialist extremists into City Hall with him.

What businesses would want to remain here?

The irony, of course, is that if they leave, they’ll take their tax revenue and jobs with them.

Where will Mamdani & Co. get the money to fund all the freebies he wants to offer when that happens?
