Britax is a global corporation with a manufacturing hub in Fort Mill, South Carolina where it employs 300. It is there that the company creates car seats for children. Unknown is how long it will continue to.

While it’s surely risky to draw immediate correlation, James Politi of the Financial Times recently reported that Britax is thinking about relocating. The impetus for relocation is the tariffs the Trump administration has levied on foreign goods.

Tariffs Are Taxes

It seems the car seat business is a low margin affair, and beginning in 2018, Britax suddenly faced a 10 percent tariff on the textiles it imports to cover its seats. The tax moved up to 25 percent after a breakdown of trade talks this past May, and then this month a new, 15 percent tariff on metallic inputs such as harnesses and buckles was imposed. The taxes levied on imported inputs Britax relies on to complete its car seats has put it at a disadvantage vis-à-vis car-seat makers located outside the U.S. According to Politi, foreign producers of the seats enjoy a tariff exemption care of the “U.S. trade representative for some, but not all, safety products.”

It’s all a reminder of the basic truth that tariffs are a tax, plain and simple. Not only do they harm the businesses they’re naively assumed to protect by shielding them from market realities, they’re paid for by other businesses reliant on imported inputs; meaning all businesses.Tariffs raise the cost of doing business, which means they’re a tax on earnings. It’s all very simple.

Figure that something as prosaic as the pencil is a consequence of global cooperation, so imagine by extension just how much a car seat is the end result of production taking place around the world. In this case, the Trump administration falsely “protects” textile and metal companies located in the U.S., and the bill for the protection is sent to companies like Britax. The tax paid by the latter has shrunk its already slim margins even more.

Interesting about tariffs is that they bring about agreement among people with differing ideologies. President Trump’s NEC head Larry Kudlow strongly believes that tariffs are a tax, as does Democratic presidential hopeful, and frequent Trump critic, Pete Buttigieg. Tariffs raise the cost of doing business, which means they’re a tax on earnings. It’s all very simple.

Currency Devaluation Is a Tax

Which is why the quietude about President Trump’s dollar stance is so strange. As some know, Trump would like a weaker dollar. He incorrectly believes a debased greenback would make U.S. industry more competitive. Except that it wouldn’t, and one reason that a falling dollar wouldn’t enhance the health of U.S. corporations is because currency devaluation is 100 percent a tax.

Tariffs raise the cost of importing simply because a 10, 15 or 25 percent tariff is a tax above and beyond the price of the imported good in question. When Trump imposes tariffs that are paid for by importers, the U.S. Treasury ultimately collects the proceeds of same.

If the dollar is devalued, so must shrink the value of the dollars a corporation takes in.

With devaluation, much the same is at work. In this case, devaluation of the dollar logically raises the cost of importing foreign goods. It also raises domestic prices, but that’s another piece of commentary for another day. For now, it should be said that money is an agreement about value. If the agreement is shrunk such that it means something different, or is exchangeable for less, it’s only logical that the cost of importing foreign inputs is going to rise unless foreign producers are willing to accept haircuts for what they send our way.

And what about the U.S. Treasury. While it doesn’t collect the “proceeds” of dollar devaluation in the way that it does the false fruits of tariffs, the result is the same. A dollar is yet again an agreement about value. If the exchangeable value of the dollar is shrunk, so shrinks what Treasury owes.

Devaluation is most certainly a tax, and it has a very similar impact on corporations as a tariff. Not only does it raise the cost of purchasing the inputs necessary to produce market goods, it at the same time shrinks company earnings. If the dollar is devalued, so must shrink the value of the dollars a corporation takes in.

The Value of the Dollar Can Change

For those who think a dollar is a dollar is a dollar, think again. No one earns dollars, as much as they earn what dollars can be exchanged for. There’s a big difference. If the value of the dollar decreases, so must we decrease the value of a dollar earned by a business.

The previous paragraph helps explain why periods of dollar devaluation (think the 1970s, think the 2000s) correlate with greatly subdued stock-market returns. If the market value of a company is a speculation by investors about all the dollars a company will earn in the future, it’s only logical that a devaluation of the currency unit that investors use to attach a value to corporations is going to negatively impact share prices.

Yes, a tariff is a tax. And so is devaluation. Why don’t policy types and candidates for public office speak up about the other devaluation?

Taking the previous point further, companies logically grow via investment; be it in people, processes, and nearly always both. Investors, as readers of this column well know, are buying future dollar returns when they put money to work. Devaluation logically shrinks the exchangeable value of those returns. Again, it’s a tax.

Which leads to the final question of this piece: why do honest members of left and right readily acknowledge the tax that is the tariff, all the while ignoring the tax that is devaluation? In each instance policymakers are shrinking the value of individual and corporate work, all the while shrinking what individuals and corporations can get in return for their work.

Yet Trump’s tariffs bring forth all manner of reasonable (and sometimes unreasonable) hand wringing, while his calls for a shrunken dollar happen mostly without comment. This despite them being the same. Yes, a tariff is a tax. And so is devaluation. Why don’t policy types and candidates for public office speak up about the other devaluation?
