Mayor Bill de Blasio, who on his quixotic presidential quest has argued that wealthy Americans should pay a healthy 70% slice of their income in taxes, has pledged to help save an iconic Brooklyn pizzeria that … didn’t pay its taxes.

Wednesday morning the mayor tweeted, “Di Fara is THE best pizza place in New York City. It MUST be saved. I’m ready to do anything I can to get them reopened — as are thousands of New York City pizza-lovers. My team and I are looking into how we can help resolve this situation.”

Setting aside the question of whether a Red Sox fan is qualified to determine the best pizza in New York, de Blasio might consider making New York City a more inviting place for all small businesses instead of picking winners and losers like pieces of pepperoni on a pie.

Time and again, de Blasio has supported and passed laws that put the screws to small business owners across the city. The $15 minimum wage and the unfunded paid-vacation mandate are just two examples of policies that are hurting the city’s laundromats, bodegas and slice slingers. If the mayor really wants fewer Chick-fil-A’s, he ought to be helping local stores compete.

If Hizzoner wants to rally around Di Fara and help it find a solution to its financial problems, that’s all well and good, but obviously, it will do nothing to solve the underlying problems, many cooked in his own oven, that beset mom-and-pop shops struggling to survive.

The tone deafness of delivering some kind of exception for the purveyors of his favorite pizza while his policies choke small businesses is jarring.

Instead of worrying about one pizza parlor, we need a mayor focused on helping the thousands of others that employ New Yorkers and deal out our slices to fold so that they do not.
