President Trump’s barrage of tariffs has produced in response a barrage of criticisms. Some take the form of an appeal to expert authority: economists, we are told, agree that tariffs are bad policy, and thus the administration’s recent “Liberation Day” tariffs are prima facie irrational.
Such claims are, of course, exaggerations. At least some economists—even if unorthodox ones—have supported the use of tariffs in certain situations. Indeed, it is hard to see how economists can claim to reject tariffs in principle since they as a class do not reject all government interventions in the market. We rarely hear that economists agree in condemning the income tax or social assistance to the poor even though these policies are market interventions.
Nevertheless, suppose all economists actually agree that tariffs should be rejected in principle. What then? It does not follow that tariffs are necessarily bad public policy. Economists specialize in the conditions that make for an efficient and prosperous economy—but that is not the sole aim of government policy. A strong economy is not the same thing as a strong and secure political community. The latter is the aim of the statesman, who must take a more comprehensive view of things than the scholar who specializes in economics.
