The mill, the tariff, and the consumer who pays for both

The New York Post reports that the Trump administration has announced the largest steel plant in American history, to be built in Iowa — and notes, in the same breath, that 50% tariffs on steel have driven up construction prices across the country. That juxtaposition is not incidental. It is the whole argument in miniature.

Let me be plain about what a tariff of this kind actually does. It is not, in the first instance, a tax on the foreign producer. The foreign producer sells at a world price; it is the domestic importer — and behind the importer, every manufacturer, every builder, every consumer who purchases anything made of or with steel — who pays the difference. The tariff is a private transfer, arranged by public law, from the many who buy steel to the few who make it. This was true in my own century of the Corn Laws and the navigation acts; it is equally true today.

The defenders of such a measure will say: but we now have a great mill, and employment, and a domestic capacity that cannot be taken from us by a foreign rival's pricing. I do not dismiss this. The defense of the nation is a legitimate public purpose, and a sovereign who is genuinely persuaded that steel independence is a strategic necessity may have a case — a narrow, specific, military case. I argued in The Wealth of Nations that the defence of Britain justified the navigation acts, even at an economic cost. The argument from security is real. But it must be made honestly, not dressed in the language of prosperity.

For here is the difficulty. The Post tells us the administration is "focusing on domestic manufacturing ahead of the Nov. 3 midterm elections." That is the sentence I would ask every reader to weigh. When the timing of industrial policy is governed by the electoral calendar rather than by any strategic audit, we are no longer in the realm of national defense. We are in the realm of what I called the "mercantile system" — the arrangement by which a coalition of producers, having made themselves useful to the sovereign, obtain by statute what they could not obtain by competition. The consumer, dispersed and unorganized, pays in silence.

I would ask one further question about the mill itself. A single very large plant, built under the shelter of a tariff, in a single state, producing a single commodity — this is a fine thing for the workers and the owners of that plant. But the division of labor, and the wealth that flows from it, depends on the freedom to specialize across an entire economy. The builder in Texas, the automaker in Michigan, the appliance manufacturer in Ohio — all of them now pay more for their primary input than their competitors in countries without a 50% steel tariff. The gain is concentrated and visible; the loss is diffuse and invisible. Politicians, I observed, will always find it easier to point to the mill than to explain the empty workshop.

The institutional question, then, is this: what framework ensures that a policy announced as strategic necessity is actually subjected to that test? A public accounting — not a press release timed to an election, but a genuine cost-benefit reckoning, conducted by an independent body, that sets the price paid by consumers against the security benefit claimed by the sovereign — would be a worthy public institution. Without it, the largest steel mill in American history may be exactly what its sponsors claim, or it may be the largest subsidy in American history dressed in iron. The consumer deserves to know which.
