Ironically, one symptom of deindustrialization is that many commenters have never actually managed a physical business. So. Suppose your US company imports 1M of high quality parts, and adds in its own components to produce finished goods sold for 1.2M per batch. Your gross profit is $200k per batch. But wait! Suddenly a new 30% tariff is imposed on that 1M of parts. You now have to fork over $300k to customs before you sell anything. That’s cash you probably don’t have. Oh, and even if you do sell everything, you’re now losing $100k per batch. With a sinking feeling, you realize your profitable business which you somehow managed to keep in America all these years has suddenly become unprofitable. You post online about how bad this is but get shouted down by an angry mob, convinced that capitalists like you should die. You can’t tell nowadays if they’re on left or right. Moreover, you don’t have the time, money, skills, or tools in house to build that 1M of parts yourself. You are being asked to do the equivalent of growing a maple tree when all you needed was a little maple syrup. So now you are faced with several tough choices. (1) First, you may need to go into debt or fire people to quickly come up with the $300k in cash to pay for these surprise tariffs at customs. Even if the tariff might go away, it might not, so you have to get the cash somehow or risk having your shipment impounded. (2) Next, you might need to reduce quality to stop losing $100k on each batch. You could order the lower quality $750k parts, grimace and pay 30% tariff at customs, and hope you can build and sell for the same price of 1.2M per batch despite the lower quality. (3) Alternatively, you could keep the quality parts at 1M and instead raise prices to 1.5M per batch to get back your original margins of $200k per batch, which you need to pay employees after all. But that’s a big hike that your customer will probably not welcome, given that he’s likely dealing with his own tariff shock. So: these tariffs don’t really give an incentive to build in the US. Because it’s far more expensive to build a screw factory than to pay even high tariffs on a foreign screw. Instead what they likely mean is debt, layoffs, lower quality, and higher prices for any US company that buys parts abroad. Just to understand how common that is:
