New York City Mayor Zohran Mamdani has been accused of waging "class war" and engaging in demagoguery following the release of a list containing the names, addresses, and property values of hundreds of thousands of homeowners. The administration claims the release was for "transparency" regarding the city's new pied-a-terre tax, but critics argue it was an intentional act to embarrass and frustrate property owners.

The Department of Finance reportedly sent notices to only 17,000 owners of homes suspected of not being full-time residences and valued above the tax cutoff lines. Despite this, the mayor's office allegedly urged the department to release a broader list, which the New York Post described as "at least 95% inaccurate" by the department's own measures.

Reports indicate that even many of the tax bills were sent to the wrong individuals, who now have three weeks to prove their residency. Critics contend that releasing "sloppy, mislabeled data revealing personal information" is not transparency but rather an "intentionally opaque and confusing" tactic.

The underlying motivation, according to critics, is to "embarrass and frustrate people who have the bad taste to own something in a city ruled by socialists who believe that all housing should be public housing." The mayor's office has also been criticized for circulating videos of the mayor warning "absentee fat cats" to check their mail.

This action is being compared to instances where other city agencies, such as the NYPD or the Human Resources Administration, do not release lists of arrests or applications for assistance. The argument is that it is not the government's role to "wage a campaign of embarrassment or stir up resentment against segments of the population."
