Ben Shapiro reminds National Review Online readers about Karl Marx’s malevolent role in world history.

This week marks the birthday of one of history’s worst human beings, Karl Marx. Just because Marx’s philosophy would lead directly to the deaths of 100 million human beings over the course of a century, the imprisonment of tens of millions more in gulags and re-education camps from Russia to China to Vietnam to Cambodia to North Korea, and the oppression of hundreds of millions more hasn’t dissuaded those on the modern western left from embracing Marx’s bloody legacy. Realizing, however, that embracing Communism itself might alienate those who remember the Berlin Wall, today’s Marxists rally instead for identity politics. In the pages of the New York Times — the same newspaper that in the past two years has run opinion pieces endorsing Communism’s impact on female empowerment and female sexual activity and its inspirational effects on Americans — Kyung Hee University associate professor of philosophy Jason Barker celebrated Marx’s birthday, writing, “Happy Birthday, Karl Marx. You Were Right!”

What, exactly, was Marx right about?

He wasn’t right about economics — his theory of economics is tripe. He wasn’t right about history unfolding as a glorious Hegelian progression toward a socialist utopia either. But according to Baker, he was right about one thing: The dispossessed of the world would unite to change human nature by changing the system of oppression under which they lived. Marx, says Baker, was right about class exploitation — the rich exploiting the poor. …

… Instead of a revolution of the proletariat, then, Marxism now seeks a revolution of the victims — the various groups of dispossessed who feel that the system has been stacked against them. And it is far easier to unite such groups around intersectional themes than it is to unite them around income disparity. There may not be any serious brotherhood between those who don’t earn much money, but pure tribalism forms lasting ties — and Marxists are happy to mold those tribes into a new nation of rebels.
