President Biden’s “humane” open-border policies are meant, allegedly, to give illegal migrants a chance at a better life. 

In New York, a city enduring a fiscal and social crisis caused by those policies, this means driving them into prostitution. 

Corona, Queens, has seen the explosion of a red-light district, rife with open streetwalking and brothels, over the past months — an ugly blooming that Mayor Eric Adams attributes to the migrant influx. 

“This is what happens when you create an atmosphere that people can’t provide for themselves,” the mayor correctly told reporters Tuesday. “You can’t work, you can’t provide … and have to turn to illegal activities to do so.”

He’s dead right, of course: More than 100,000 migrants have arrived here just in 2023. 

The cost to the city for feeding, housing and educating them is projected to hit $12 billion by the end of fiscal 2025 assuming inflows level off. (They won’t, barring a Biden loss next November.)

But Adams left another important question unasked. 

How does flourishing prostitution square with the humanitarian goals Biden and his entire party endlessly trumpet as their motives for wrecking border enforcement and waving in literally millions?

Migrants to the United States face (and are often killed by) cartel-backed human traffickers along the perilous route here, only to be forced into a profession infamous for the risk of trafficking it involves. 

And it’s not just prostitution. 

Gotham’s illegal migrants live and work in a massive economic gray zone generally. 

Mother-and-child teams of candy sellers are now a sadly familiar sight in the subways. 

Given the crime crisis underground, that’s yet another black mark on the president’s record as a “humanitarian” when it comes to border issues. 

The most visible and widespread gray-market job illegal migrants find in the city is likely in the app-based food delivery sector. 

Some make as much as $3,000 a month schlepping dinner to the wealthy liberals whose support helped make Biden’s border disaster real. 

Images from the Roosevelt Hotel — a once-tony Midtown joint now converted into a shelter — with a row of electric scooters parked out front symbolize perfectly the dark absurdity of Biden’s policies. 

Come to America and find a better life runs the “invitación” from Biden, DHS head Alejandro Mayorkas and their chorus of enablers.

The unspoken coda: You’ll work a dangerous, illegal job and have no permanent place to live. 

But even the deep-blue Empire State is sick of Biden’s border failure, with nearly two-thirds of voters here blaming him for the city and state’s migrant ills. 

It’s a warning sign that the president ignores at his deadly political peril. 

Yet somehow, we suspect even that won’t be enough to wake him up.
