Consider the butcher. He spends a lot of time killing animals. Do those who find this morally questionable tend to call butchers personally to account? I’ve not heard of that—though it may happen—but I do know that many direct their energy to education of those who demand meat.
Consider, say, a fireman on an old train. His job involved setting fire to a bunch of coal, thus soiling the skies. Did people blame him for this air pollution? Or did they think: “Hey, that’s just his job. It’s the result of the choices of many people that we have trains.”
In these examples and others I can think of, we tend to hold individuals less accountable for actions that are inextricably bound up with the successful completion of job-related tasks. A classic example is that of the soldier following orders; yes, we often tend to think a soldier should listen to his conscience, but we also often leave way for the explanation that the soldier accepts the moral authority of his superiors.
Sometimes, commentators inveigh against politicians—against practically all of them, as a class—on moral grounds, as in this example from several years back:
I challenge anyone to argue that the behavior of any of the major candidates…is admirable. Everyone knows that each serious candidate trims, waffles, is duplicitous, has his or her finger in the winds blown by polls, and wants to be President not because of any burning itch to help fellow human beings but because the job comes with all the trappings, and much of the power, of royalty.
I see two distinct complaints there: that politicians play games with words, and that politicians act from self-interest. Economists and wise liberals in general should dismiss the latter complaint out of hand; there’s often nothing wrong with acting largely out of self-interest. That would leave us with the first complaint, that politicians are tricksters.
What if it’s the case that we live in a world where there are some serious interpersonal conflicts that cannot be resolved via honest back-and-forth discussion to mutual agreement? For the means to bring about the necessary resolutions, then, we would have second-best choices such as violence and duplicity. I venture to guess that many of us would choose duplicity over violence as a means of resolving a dispute.
If those sorts of conflicts sometimes crop up, and if “politician” is the occupation of one who resolves such conflicts under a division of labor, then, well, it’s just a job, not a mark of moral inferiority. Can a commentator rightly challenge politicians to avoid duplicity when it seems needless or counterproductive? Sure, without a doubt. But one should also recognize that it’s intrinsic to much of their work.
