TGIF: Tariffying Trade-Warmonger Trump

"The word tariff, properly used, is a beautiful word. One of the most beautiful words I’ve ever heard. It’s music to my ears." —Donald Trump

The once and possibly future president threatens to wage economic warfare against countries and companies everywhere if they don't knuckle under to his nationalist demands. He promises to impose tariffs on American firms that calculate that moving operations to Mexico or other foreign locations makes good business sense. He's also ready to strike at allied countries that irritate him by, say, slighting the dollar. (Watch or read his economic-policy speech.)

To his credit he promises to lower taxes on investment and to cut the regulatory burden. He also wants lower energy prices, which would be good all around, but exactly how matters. He's no laissez-faire advocate.

At any rate, Trump's determination to restore the American economy to what it was when much of the world lay in ruins after World War II suggests that, despite all the changes since then, he would much do more than de-tax and deregulate. For example, he promises to lure foreign companies here. Again, how? His government would no doubt play an active role in what should be private matters. He's already promising to make the taxpayers pay for business infrastructure projects. As he said about the audio industry, "It’ll be like it was 50 years ago." He won't be able to turn the clock back, but he can do much damage trying.

This is economic nationalism. He sees the world as an arena in which countries—as if they were companies—compete against one another: for one country to win, the others must lose. Powered by this worldview, Trump wants to be the CEO of the company known as the United States.

His vision is dangerously wrong. The world is not an arena in which countries compete with one another, where one nation's gain is the others' losses. That American manufacturers routinely buy foreign-made materials, tools, machines, and semi-finished products demonstrates this. We have a global division of labor in which capital, resources, and all kinds of goods have been able to move across national boundaries fairly freely as market forces require. As a result, world poverty has diminished unbelievably, and Americans are richer than ever. (The rough spots can be attributed to unabated domestic government intervention.) This progress has been in the making for about 80 years, but the liberalization responsible for it has been reversed recently—to the world's detriment.

Trump understands none of this, and he has no incentive to do so. Since entering politics, his demagogic promise has been to wreak vengeance on the world for, as he sees it, taking advantage of the United States. This is his aggrieved-nation shtick. The U.S. government has been the biggest bully since 1945, but Trump would have gotten nowhere politically had he promised to stop throwing America's weight around. Instead, he portrays the United States as a pitiful giant that has been everyone's chump. It's nonsense.

What's foreign to Trump's mentality is any notion of an unplanned, spontaneous market order built on individual freedom and choice, which is at the heart of sound economics. He must see himself as a hands-on CEO who can solve any problem. That's the last thing we need. He should read Leonard Read's "I, Pencil." (The video version is here.)

In a word, Trump is an economic warmonger, a not-too-distant cousin of a regular warmonger. As the old free traders said, "When goods can't cross borders, soldiers will."

It would be one thing if Trump were promising to shrink the government so much that businesses everywhere wanted to flock to these hospitable shores. But his "New American Industrialism" is an old-fashioned industrial policy in which he or his team of experts would pick winners to carry out his glorious vision. Which firms and industries get protected or subsidized and which don't? Those decisions would be made on a political, not an economic, basis. The problem is that Trump and his experts could not know what they would need to know to carry out their plan. Only the free market—through the unhampered price system—can produce that knowledge, which would be widely dispersed, often tacit, and therefore unavailable to a central bureaucracy. Even the great Donald Trump cannot defy the laws of economics.

What would Trump do if other countries tried to make their economies more hospitable to the world's businesses, say, through rigorous liberalization? Would he up the statist ante? The economic nationalist is not likely to back down.

No one should be surprised that Ludwig von Mises—the unparalleled champion of peace through full liberalism—had much to say about economic nationalism. In Human Action, he wrote: "Economic nationalism is incompatible with durable peace.... It is an illusion to believe that a nation would lastingly tolerate other nations’ policies which harm the vital interest of its own citizens."

Trump might endorse Mises's last sentence, but he'd be missing the point. Other countries would respond to Trump's program. If he responds in turn, he will hurt Americans for sure (and perhaps foreigners). Consumers will largely pay the tariffs and, along with import-using American manufacturers, face higher prices. That's the point!

Freedom in the economic sphere, as in all other spheres of life, is in the deepest interest of all citizens. Protectionism and other interference are not. One industry or firm may calculate that if it can win protection from the state, it will prosper even if others suffer. But protection granted to one interest will encourage others to ask for it too. Now the original gain begins to dissolve. As Mises put it in Socialism: An Economic and Sociological Analysis,

A system which protects the immediate interests of particular groups limits productivity in general and, in the end, injures everybody—even those whom it began by favouring.... The greater the protection afforded to particular interests, the greater the damage to the community as a whole, and to that extent the smaller the probability that single individuals gain thereby more than they lose....

[I]f all particular interests were equally protected, nobody would reap any advantage: the only result would be that all would feel the disadvantage of the curtailment of productivity equally. Only the hope of obtaining for himself a degree of protection, which will benefit him as compared with the less protected, makes protection attractive to the individual. It is always demanded by those who have the power to acquire and preserve especial privileges for themselves. [Emphasis added.]

Why would they all lose? Because, as we've known at least since David Ricardo formulated the law of comparative advantage (or what Mises called the law of association), the division of labor and free exchange bring specialization that yields immense gains to all—even when an individual, group, or nation is less efficient than others at producing a whole range of goods.

Trump displays the words Made in the USA onstage. The wiser course is to specialize and to trade with others rather than trying to produce everything. Market price signals, not Trump, should be our guide. If the frontiers were closed to foreign goods, Mises wrote in Socialism, "Capital and labour would have to be applied under relatively unfavourable conditions yielding a lower product than otherwise would have been obtained."

Thus Trump's blustering warfare would shrink incomes and risk conflict by disrupting the signals that channel productive energies to where consumers most want them.
