The Adams administration just ditched a new class of rookie school-safety officers — and Hizzoner says maybe parents should step in and take up the slack.

Talk about your intersectionality!

Here we have declining public safety colliding with a national border breakdown — and, as usual, the collateral damage falls heavily on hard-working folks doing their best just to get by.

And the pain certainly won’t be confined to parents concerned about classroom safety — not with tens of thousands of penniless migrants boring a multi-billion-dollar hole in the municipal fisc.

Specifically, the city just deep-sixed a class of 250 new school-safety officers — civilians who work with the NYPD to maintain order in city schools.

Not surprisingly, this has raised parental concern at a time when random violence has become a Big Apple plague. Most schools probably are reasonably safe, sure, but random is random — it’s hard to predict, almost impossible to prevent and fewer officers only compounds the problem.

Thus the mayor’s proposed, um, solution: “We’re going to be leaning into parents and parent groups to do some volunteerism,” he said Tuesday.

Maybe Adams is just talking through his hat here — he does that a lot and, really, he’s had some personal distractions lately — but he probably hasn’t thought this one through.

After all, former Marine Daniel Penny “did some volunteerism” last May, stopping a violent vagrant on behalf of endangered F Train straphangers, and he’s under indictment for manslaughter. Has Adams vetted his scheme with Manhattan DA Alvin Bragg?

Extreme? Maybe.

But one point of a formal public safety system is to discourage private citizens from settling their own beefs; promoting what amounts to vigilantism, no matter how it’s gussied up, is a very bad idea.

On the other hand, maybe Adams is just indulging the time-honored political practice of scaring the bejeezus out of the citizenry to pave the way for tax increases and related chicanery.

Usually the pols just threaten to shut down libraries and firehouses to bring the people around; the cuts rarely happen, but the tax hikes usually do; the pols quietly congratulate each other for their cleverness, and everything is peachy until the next time the dough runs low.

But if that’s the plan, this time it’s unlikely to work.

This time, sanctuary-city bushwa intersects with the inability of cities to print their own money.

This time, the progs have dug a hole too deep for sophistries to fill — as will become clear when New York’s governmental budget-writing season begins in January.

The pain will be deep, real and lasting. That is, libraries, firehouses and — yes — school safety will be the first to go, but it’s can’t end there.

If the border hopping stopped tomorrow, New York City would still be looking at an estimated $12 billion migration-driven budget gap — far too wide for tax increases alone to fill.

Yes, the solution lies in Washington, with a restoration of national border integrity.

But when Adams started talking about that, he found himself up to his ears in FBI agents — a stark fact unlikely to have gone unnoticed elsewhere, by the way — so it’s much safer for him to shut his mouth and dig deeply into school safety.

For starters.

But, one more time for emphasis, no way it’s going to end there.
