The thing about old socialist politicians, like Bernie Sanders who is 75 and Britain’s Jeremy Corbyn who is 68, is that they have youth on their side.

Across the pond, the youth vote allowed the British Bernie Sanders to do a lot better than the so-called experts thought he’d do in the recent general election. Here in America, we all know how the millenials went ga-ga for our Bernie. He got more millennial votes in the primaries than Hillary and Donald – combined.

I recently made a reservation for dinner at a restaurant in a very liberal city in North Carolina – using only my first name, Bernie — and the young hostess was a little disappointed that it wasn’t Bernie Sanders who walked through the door. I know this because she told me she was hoping it was Sanders who was coming in for dinner. She had a pleasant smile on her young face the whole time, but a pleasant smile is pretty much obligatory in the South, especially when you’re disappointed.

The fact is a lot of millenials actually like socialism. A 2016 poll conducted by Harvard showed that a majority of voters between 18 and 29 — 51 percent — rejected capitalism while a third said they supported socialism.

And a 2011 Pew poll of millenials revealed that there actually was more support for socialism than capitalism. Forty-nine percent had positive views of socialism while only 46 percent had positive views of capitalism.

How could this be? Doesn’t everybody know by now that socialism doesn’t work? Haven’t they heard the famous Margaret Thatcher line that, “The trouble with Socialism is that eventually you run out of other people’s money”?

If they did hear it, they haven’t taken it seriously. In a New York Times op-ed that ran under the headline “Why Young Voters Love Old Socialists,” Sarah Leonard, a 29-year old editor at the far left Nation magazine explains: “[W]ithin this generation, things like single-payer health care, public education and free college – and making the rich pay – are just common sense.”

Of course it is. Until you run out of other people’s money.

Let’s acknowledge the obvious: Getting free stuff is fun – mainly because … it’s free! So it shouldn’t be a shock that young voters fell head over heals for a (democratic) socialist like Bernie Sanders who promised them a “free” college education paid for by those miserable rich people who have too much money anyway.

And just imagine if the Democrats somehow manage to come up with a young, progressive, attractive, even sexy version of the old socialist from Vermont next time around. Republicans – and more importantly, America – could be in serious trouble.

But here’s where millenials get off easy: No one is calling them out for what a lot of them are – which is, greedy.

Here’s how Thomas Sowell, the great thinker from California put it: “I have never understood why it is ‘greed” to want to keep the money you’ve earned, but not greed to want to take somebody else’s money.”

So what we have is a greedy generation that feels entitled to all sorts of things including other people’s money. If this is the future, give me the past.

George Bernard Shaw had it right a long, long time ago when he said: “A government that robs Peter to pay Paul can always depend on the support of Paul.”

Who knew that Paul was 25 and voted for Bernie?

Memo to millenials: You won’t be young forever. And when you get older and have jobs and pay taxes, who do you think is going to pay for all those “free” goodies you once demanded when you were young and – forgive me — not-too-smart? The bill for all that “free” stuff — along with interest — is going to come due at some point, right? And the next generation of millenials is also going to want “free” stuff. You’ll be paying for that too.

One more piece of wisdom from Thomas Sowell, wisdom that young voters in the embrace of socialism might want to consider: “If you have been voting for politicians who promise to give you goodies at someone else’s expense, then you have no right to complain when they take your money and give it to someone else.”

Having second thoughts yet, millenials, about the virtues of socialism?
