Policy makers struggling to understand the barrage of financial panics, protests and other ills afflicting the world would do well to study the works of a long-dead economist: Karl Marx. The sooner they recognize we’re facing a once-in-a-lifetime crisis of capitalism, the better equipped they will be to manage a way out of it.

The spirit of Marx, who is buried in a cemetery close to where I live in north London, has risen from the grave amid the financial crisis and subsequent economic slump. The wily philosopher’s analysis of capitalism had a lot of flaws, but today’s global economy bears some uncanny resemblances to the conditions he foresaw.

Consider, for example, Marx’s prediction of how the inherent conflict between capital and labor would manifest itself. As he wrote in “Das Kapital,” companies’ pursuit of profits and productivity would naturally lead them to need fewer and fewer workers, creating an “industrial reserve army” of the poor and unemployed: “Accumulation of wealth at one pole is, therefore, at the same time accumulation of misery.”
