NYT: One Nation Under Guard

Another dubious first for America: We now employ as many private security guards as high school teachers — over one million of them, or nearly double their number in 1980. And that’s just a small fraction of what we call “guard labor.” In addition to private security guards, that means police officers, members of the armed forces, prison and court officials, civilian employees of the military, and those producing weapons: a total of 5.2 million workers in 2011. That is a far larger number than we have of teachers at all levels.
What is happening in America today is both unprecedented in our history, and virtually unique among Western democratic nations. The share of our labor force devoted to guard labor has risen fivefold since 1890 — a year when, in case you were wondering, the homicide rate was much higher than today.

Does the graph show that inequality causes a country to devote more of its labor force to guard labor? It is hard to be sure. It could be that people with a strong commitment to economic justice are, for some unknown reason, also more law-abiding, explaining the difference between Denmark and the United States. But the correlation evident in the graph could be evidence that economic disparities push nations to devote more of their productive capacity to guarding people and property. Fear and distrust of one’s neighbors and fellow citizens fuel the demand for guard labor. Economic disparities can contribute to both. Among the countries shown, a common measure of distrust of strangers is strongly correlated with both the guard-labor fraction and inequality.
Social spending, also, is strongly and inversely correlated with guard labor across the nations shown in the graph. There is a simple economic lesson here: A nation whose policies result in substantial inequalities may end up spending more on guns and getting less butter as a result.
