It’s not often that a president delivers exactly what he promised for the US economy, but this one has. Specifically, President Trump has delivered not just solid job growth, but also rising wages. This when his critics called it impossible.

March saw nonfarm payrolls grow by 196,000, the Bureau of Labor Statistics reports — a major rebound from the slowdown in the first two months of the year. And wages grew 3.2 percent over the last 12 months, markedly faster than inflation.

Unemployment was 3.8 percent in March, and has been at or below 4 percent for 13 straight months. This is what economists usually call “full employment,” but the gains keep coming in part because millions who’d given up on even looking for work — and so were no longer counted as “unemployed” — have rejoined the workforce.

All this even as Democrats have routinely denounced Trump in the same terms they’ve slammed every Republican for decades, as merely favoring the rich.

Manufacturing has added 480,000 jobs since Trump’s election, and 209,000 jobs in the past 12 months. And that boom is something that both President Barack Obama and top liberal economist-pundit Paul Krugman insisted couldn’t happen.

Literally: In June 2016, Obama slammed Trump’s promises as impossible, saying the then-candidate would need a “magic wand” to deliver. Manufacturing jobs “are just not going to come back,” he warned — after six months when they’d fallen by 31,000 under his policies.

A month after Election Day 2016, Krugman wrote of factory work: “Nothing policy can do will bring back those lost jobs. The service sector is the future of work; but nobody wants to hear it.”

It’s certainly true that long-term trends favor growth in the service sector over that in manufacturing worldwide — but that leaves plenty of room for new US factory jobs, as well as service ones.

Trump’s formula was pretty simple: Ending the Obama-era wave of ever more regulation, while rolling back many of the most senseless rules, and cutting taxes.

Plus two major breaks from recent Democratic and Republican policy.

First: His trade approach has always been aimed at boosting US employment, especially in manufacturing. Critics note that Trump’s tariffs have hurt some US industries while helping others, but not enough to stop the gains noted above. And the tariffs are just a means to the end of fundamentally rewriting trade relations — the disruptions should end as new trade deals are finalized.

Second: Trump’s toughness on illegal immigration is also (in part) about protecting American workers from competitors who’d work for less.

As Charles Gasparino noted in Saturday’s Post, this last actually has the New York Times bewailing the rise in construction wages because of a labor shortage. The building trades are notorious for employing the “undocumented”; now they’re feeling a squeeze thanks to Trump.

The Times paints it as “a terrible burden for wealthy construction companies and contractors,” Gasparino notes — when it’s a clear win for the US working class.

Lord knows, there’s plenty more to be done. Presidential adviser Ivanka Trump and chief economist Kevin Hassett continue to push the private sector to up its job-training game, which is vital to continued employment growth.

(Government training programs, sadly, don’t deliver the same payoffs.)

Even the president’s push for criminal justice reform plays a role here: People leaving prison need work, and this economy needs the workers. It’s all about making American society healthier.

Bottom line: Trump has been pursuing a clear, coherent vision from the start, one his opponents insisted couldn’t work — and it’s doing exactly what he said it would.
