Klein adds the third element to our story, which he calls “governmentalization.” Words having to do with experts have shown a steady rise. So have phrases like “run the country,” “economic justice,” “nationalism,” “priorities,” “right-wing” and “left-wing.” The implication is that politics and government have become more prevalent.

So the story I’d like to tell is this: Over the past half-century, society has become more individualistic. As it has become more individualistic, it has also become less morally aware, because social and moral fabrics are inextricably linked. The atomization and demoralization of society have led to certain forms of social breakdown, which government has tried to address, sometimes successfully and often impotently.

This story, if true, should cause discomfort on right and left. Conservatives sometimes argue that if we could just reduce government to the size it was back in, say, the 1950s, then America would be vibrant and free again. But the underlying sociology and moral culture is just not there anymore. Government could be smaller when the social fabric was more tightly knit, but small government will have different and more cataclysmic effects today when it is not.

Liberals sometimes argue that our main problems come from the top: a self-dealing elite, the oligarchic bankers. But the evidence suggests that individualism and demoralization are pervasive up and down society, and may be even more pervasive at the bottom. Liberals also sometimes talk as if our problems are fundamentally economic, and can be addressed politically, through redistribution. But maybe the root of the problem is also cultural. The social and moral trends swamp the proposed redistributive remedies.

Evidence from crude data sets like these are prone to confirmation bias. People see patterns they already believe in. Maybe I’ve done that here. But these gradual shifts in language reflect tectonic shifts in culture. We write less about community bonds and obligations because they’re less central to our lives.
