For most of the 20th century, favorably mentioning the works of Karl Marx has been a quick road to being run out of polite society in the United States. But I've just finished a long trip through the first volume of Das Kapital, as well as several of his other works, and at the risk of tempting the RedScareBot, I think there are some genuinely valuable insights to be had in 2014, almost 150 years after it was first published.

Marx has been maligned mainly by association with the totalitarian dictatorship of the Soviet Union. However, Das Kapital, like most of his work, is a descriptive account of how capitalist institutions would change the politics and economy of a nation. As such a work, I see three main areas where Marx's insights are still worth considering.

First, income distribution. Marx thought that capitalism would necessarily lead to impoverishment of the masses. The greater the extent of capitalist development, he argued, the greater the poverty in the working class. In the 1950s, this would have seemed preposterous. But something has been happening to the distribution of American economic growth (graph courtesy of Pavlina Tcherneva):

The striking thing about this trend is how consistent it is. Each postwar economic expansion, almost without exception, distributes fewer and fewer of its fruits to the bottom 90 percent of the population. In the most recent one, the bottom 90 percent has gotten less than nothing on average (before taxes and transfers).

Not coincidentally, during this time the government underwent a neoliberal revolution. This set of basically orthodox capitalist policies involved cutting taxes on the rich, especially capital gains; obliterating most labor unions; making more and more social insurance contingent upon work; expanding access to credit, and so on. And presto, we got humongous and growing inequality.

This ties in neatly with the second point: Marx's views on ideology. He argued that essentially all beliefs emanated from the structure of a nation's economy, and that capitalism would obliterate all the old ideologies: "All that is solid melts into air, all that is holy is profaned," he and Engels famously wrote in The Communist Manifesto. The strong version of this thesis is clearly false — in particular, he radically underestimated the staying power of religion, not to mention nationalism and racism — but it does have some explanatory power.

Today we see this most strongly, I think, in the way world elites have behaved towards social insurance programs. Marx thought it was clearly possible to buy off the masses with transfers and social insurance, but that elites wouldn't do this because they would be hemmed in by galloping Ayn Rand-style self-legitimization. Most of the postwar 20th century seemed to prove him wrong, as nations across the world instituted generous social insurance.

But after the fall of the Soviet Union and especially after the 2008 crisis, events have been breaking down more Marx's way. In the face of a historic collapse of high capitalist institutions, right-wingers quickly regrouped and began demanding basically the whole welfare state be burnt with fire. Worse, centrist elites in practically every industrialized country developed a maddening and incomprehensible fixation with austerity, especially cutting social insurance. (ObamaCare being the important exception.) Only nutty right-wing intransigence kept Social Security and Medicare from deep cuts here in the U.S. And in Europe, elites have savaged their citizenry with almost unremitting cruelty.

Crude classist explanations of this behavior aren't convincing. But I do think there's something to the idea that the rich have become so enamored with a self-legitimizing ideology that they've grown complacent to the dangers of mass unemployment — even to their own position. Marx was right that mass unemployment is inherently destabilizing to societies; it might take the form of a nationalist, rather than socialist, movement — Hitler, after all, came to power in the midst of a depression — or something else entirely. But joblessness breeds a dangerous instability that can't be ignored.

Finally, there's Marx's account of capitalist crises. He argued that ruthless competition would cause increasingly bad economic crises because of overproduction and a corresponding collapse in profits (anticipating Keynes in many respects).

Once again, he seems partly wrong: today, profits are at records highs (which makes an interesting contrast with Piketty's work). But whether an economic crisis is accompanied by gargantuan corporate profits or by their collapse makes little difference to the people thrown out of work. The events of 2008 revealed previous smug assertions that all the problems with market institutions had been solved are a farce, and that capitalist nations have not permanently handled the problem of depression. Again, he was not wholly right. But he was on to something.

In the end, Marx is an interesting and worthwhile read with some dubious bits. But if you look past the way-too-elaborate metaphysics and some of the failed historical predictions, you find a subtle, incisive thinker. While his picture of the future of capitalism was not perfect, it's looking close enough that today's elites ought to be a lot more worried than they are.
