Leftist Democrats eyeing the White House in 2020 are plotting new ways to confiscate Americans’ hard-earned money and give it away. Claiming economic inequality is a national crisis, they want to take money from people they say have too much.

Sen. Elizabeth Warren of Massachusetts is one of several prominent Democrats pushing a wealth tax. Never mind that such a tax is both ­unprecedented and unconstitutional.

Warren says it would target only the richest one-tenth of 1 percent of the country. Maybe at first. When the federal income tax was imposed in 1913, it initially hit less than 1 percent of the country. Now half the nation pays it. So when you hear the words “wealth” tax, watch your wallet.

Warren and like-minded leftists say it’s immoral to allow people to accumulate riches, when others are needy. But when Warren is asked how she would use the money raised by a wealth tax, she insists the point is “basic fairness.”

Translation: These Dems’ tax schemes are more about punishing the “rich” than helping the poor.

You could actually call Warren’s scheme an act of class animus, because it targets a specific segment of the population — people these Democrats say shouldn’t be ­allowed to be so rich. European countries like France, riven with class animosities, have tried wealth taxes, only to see them drive away jobs and investors.

If these leftist politicians cared about the poor, they would beef up educational opportunities and job training and break the teachers’ unions’ corrupt protection of failing public schools. That would be a wiser course than confiscating wealth. Knowledge doesn’t have to be taken from one person to be given to another.

A child in poverty whose parent has a high school degree or better has a 70 percent shot at rising out of poverty, according to Brookings Institution data. If a parent is a college grad, the chances increase to 84 percent. Education beats handouts when it comes to escaping poverty.

Tell that to Democratic presidential aspirant Sen. Cory Booker of New Jersey, who wants Uncle Sam to give nest eggs to poor kids. Booker would open a $1,000 savings account for every child born in the country, courtesy of taxpayers. After that, kids in the poorest families would get up to $2,000 added each year. Other kids would get much less or zip.

What a slap in the face to parents who scrimp and save to give their own children a nest egg. Who wants to pay taxes to bankroll someone else’s kid?

Booker brags his plan would help equalize racial disparities. But in fact, it would create new ones. The average black child would end up with almost $30,000 at age 18, the average white kid only half that.

Booker’s plan also defies common sense. It doesn’t even limit the use of the money to education. Handing tens of thousands of dollars to a teenager to buy a home or take a stab at investing is nuts.

Better to supply a kid that age with a first job. Twenty years ago, more than half of teens ages 16 to 19 worked. Now only a third do, according to Labor Secretary Alexander Acosta.

Meanwhile, as more Dems enter the presidential race, the competition to stick it to the rich and spread the wealth heats up. Sen. Kamala Harris of California is promising big breaks to the lowest 20 percent of filers but nothing for couples earning $60,000 or more.

Think you’re going to be on the receiving end of these Robin Hood schemes? Nope.

If Warren’s wealth tax hits only the uber-rich, it will rake in $2.75 trillion over a decade, according to the University of California economists who devised her plan. Yet Warren is backing a list of social programs — including government-run health care for all, free college, student loan forgiveness and guaranteed jobs programs — with a total tab of $42.5 trillion. Fifteen times what taxing the uber-rich would produce.

The Dems’ share-the-wealth schemes will end up fleecing millions more people, not just what socialist Rep. Alexandra Ocasio-Cortez misleadingly calls the “tippy-tops.”

A wealth tax is a lot more intrusive than submitting a W-2, by the way. Warren’s plan calls for more IRS agents and more audits. Agents will have to value your home, your cars, furniture and jewelry every year. Yikes.

Fair warning to hard-working, successful people.
