If you’re looking for work, this is the best job market in 50 years. The economy is soaring.

But Democrats running for president are pitching plans that will destroy millions of jobs, doubling the number of people out of work. New Yorkers will be among the hardest hit.

Consider Medicare for All. It will wipe out a staggering 2.5 million health insurance and health care jobs nationwide, causing the number of unemployed people in this country to jump by almost half. Here in New York, it will throw tens of thousands out of work.

New research by Stanford University doctors in the Journal of the American Medical Association shows that Medicare for All would cause hospitals to lose a whopping $151 billion in payments the first year. Hospitals would be forced to eliminate as many as 1.5 million jobs overnight — scary news for the 385,000 hospital workers in the Empire State.

Meanwhile, Rep. Pramila Jayapal (D-Wash.), who’s sponsoring Medicare for All legislation in the House, admits it would cause 1 million insurance employees to get canned. She cavalierly suggests they can retire or get job ­retraining. Tell heartless Jayapal to do that herself.

Presidential aspirant Bernie Sanders brags Medicare for All would prevent Americans from having to choose between food on the table and medicine. Sorry, Bernie, but if your job is eliminated, putting food on your table will be impossible. Period.

You didn’t hear these bleak facts at last week’s House hearing on Medicare for All. Instead, Speaker Nancy Pelosi escorted in wheelchair-bound Ady Barkan, who is dying from Lou Gehrig’s disease. Barkan made a poignant plea for Congress to recognize health care as a right. Painful to watch — and designed to distract from the facts.

That set the tone. Dems acted more like carnival barkers than fact finders. Not one New York Democrat responded to warnings about hospitals — this city’s bread and butter — closing.

But shuttered hospitals and job losses are the reality. Right now Medicare shortchanges hospitals. Hospitals accept the low Medicare payments because they can shift their unmet costs onto patients with higher-paying private insurance. Medicare for All, however, outlaws private insurance, making that cost-shifting impossible. Everybody will be paying the low rate, and hospitals will get squeezed.

To stay open, hospitals will have to spread nurses thinner, ­reduce wages and lay off staff. That could be deadly for a patient calling for help overnight.

And bad news for this nation. Health care is America’s largest employer.

Dems are also campaigning to wipe out jobs in the oil, gas and coal industries. Every Democrat eyeing the White House is pledging to rejoin the Paris climate accord, a lopsided agreement that would hobble the US economy while barely touching the world’s largest polluter, China. Joining the accord would cost the US more than 2 million jobs by 2025, according to a division of Marsh & McLennan management consultants.

Taken together, those 2 million plus the 2.5 million jobs killed by Medicare for All total 4.5 million layoffs, almost doubling the number of out-of-work Americans. Thank you, Democrats.

Don’t they know losing a job can be a personal nightmare?

There’s more. Presidential contenders like Liz Warren also want to hike corporate tax rates and change accounting rules, making it costlier for businesses to invest in equipment and ­expand. More job killers.

When President Trump took office, there were 2 million more job seekers than openings. Now, openings outnumber ­applicants. Wages are rising, with workers at the bottom benefiting most. Female unemployment is the lowest since 1953. Credit goes largely to Trump’s deregulation, tax cuts and rules allowing companies to write off plant and equipment costs right away.

No matter how Democrats bad-mouth capitalism, the truth is wage hikes and job opportunities are moral victories. They ­enable people to become self-sufficient, raise a family and aspire to more. Presidential contender Joe Biden is campaigning to “Make America Moral Again.” Are you listening, Joe?

The Bureau of Labor Statistics says one-third of all future new jobs will be in health care. That’s unless Democrats win big in 2020 and push through Medicare for All.

A jobs boom is a good thing. Don’t let Democrats destroy it.
