So much for the “golden door.” What a shock is Mayor Adams’ announcement at El Paso that in respect of migrants “there is no room in New York.” Not only is it a sharp change from the message of the Statue of Liberty and his predecessors but from his own record. Suddenly his honor is telling migrants in Texas he wants them to work and “experience the American dream” — just, please, not at New York City.

Hizzoner had barely uttered his “keep out” than the Times signaled how the Left should deal with it. The mayor’s “positive” message “contrasted” with a “difficult” mission at the southern border” for “he is trying to increase pressure” on “President Biden to provide federal help to New York City.” He is “showing compassion” for those whose “lives have been upended” while “insisting that they stop coming to his city.” Got it?

The Gotham the Times is describing, after all, “is dealing with an influx of migrants,” with illegal border crossings from Mexico in the year ending October 2021 reaching the highest level since 1960. Any further analysis as to why border crossings have surged and President Biden’s role in managing border security is absent from the Times’ dispatch. Yet Mr. Adams notes “We expect more from our national leaders to address this in a real way.”

Contrast Mr. Adams’ — and the rest of the Left’s — confusion over migration with the posture adopted by Mayor Bloomberg during his time at City Hall. We called it, in these columns in 2007, “Bloomberg at His Best.” His message on behalf of New York was “let them come” and, he declared, “I can’t think of any laboratory that shows better why you need a stream of immigrants than New York City.”

Our own position is that New York City and the rest of the country needs more immigrants — and of all kinds. The way to welcome them, though, is not with handouts and subsidies that place a burden on taxpayers. It is, on the contrary, to take supply-side measures to stimulate growth and jobs without the kind of inflation that has been created by vast government taxing, borrowing, and spending.

We don’t gainsay the crisis at the Southern Border. The Biden approach is the worst of all options, leading to high-inflation, record illegal entries, and soaring taxes, spending, borrowing, and crime. There was a time when the mayor of New York City had what we called “automatic authority” as the gateway for “millions of immigrants, legal and otherwise.” If Mr. Adams loses that authority, it will be hard to get it back.
