Economists are used to differentiate between micro-and macro-level effects of tariffs. For each buyer of a car, import tariffs raise expectations about prices for a product. Many consumers will then decide to buy lower quality at the same price or postpone buying a new or replacement product for some time. For cars it might mean that many people will then decide to buy rather later than sooner. If thousands of people do so, the market will fall into recession overall and it will take months or years to come back to the same or a higher level. A political economy perspective has taught us that eager politicians are in favor of a short recession immediately after an election which increases the chances of reelection once the economy gets back to normal or catches up on lost growth.
The US under Trump apparently gambles with such an economic rationale. Short term inflation is already rising, interest rates stay high before the upheaval caused by tariffs stats to settle.
There is, however, another alternative mechanism at work as well. Torsten Veblen long ago hinted towards what is not called in economics the Veblen effect. Some fancy cars for example can raise prices well above others because of their cleaving image. Just because they get even more expensive the buyers of such products gain additional attention as part of a social class which does not have to care much about their additional spending. The consequences of tariffs will most likely widen the gap between those saving dearly and those able to splash out cash despite increased tariffs. The most felt consequences, therefore, will be on social inequality within the US.
