Lost in all the headlines about the federal shutdown and the war over the wall is some hugely important news: The US economy has taken a seriously worker-friendly turn.

America is enjoying its best job market in decades, with unemployment at a nearly 50-year low, people rejoining the workforce in droves and hourly wages continuing to rise.

The December jobs report showed an astonishing gain of 312,000 jobs across nearly all sectors of the economy. Manufacturing added 284,000 jobs last year, up 12 percent over 2017. Hispanic unemployment is at a record low; for African-Americans, nearly so.

As National Economics Council director Larry Kudlow says, this is “an economic boom that most folks thought impossible.”

By “most folks,” he surely means the Democrats, economists and media figures who all insisted such a turnaround could never happen. During the 2016 campaign, for example, then-President Barack Obama claimed you’d need a “magic wand” to reverse America’s loss of manufacturing jobs.

President Trump found the wand — in the form of sweeping tax cuts and deregulation that dramatically boosted business and consumer confidence.

And, again, given hope to those who’d given up on looking for work: Unemployment would measure even lower if millions of Americans weren’t rejoining a workforce they’d decided had no place for them.

Even the stock market, despite a few weeks of setbacks, is headed back up and still stands 27 percent ahead of where it stood when Trump won the White House.

Of course, the president’s critics insist it can’t last much longer. It’s certainly true that no expansion lasts forever, but the US economy still has plenty of catching up to do after the doldrums of the Obama era.

All this might have been more obvious if Trump and Republicans had campaigned last year primarily on this remarkable record. That they didn’t is a big reason Democrats took the House.

Cross your fingers that Speaker Nancy Pelosi & Co. don’t kill the golden goose.
