The left calls tariffs a sales tax on Americans. It’s not. What happens when you put a tariff on China? China eats the tariff because there are several low labor cost competitor countries. If you put an across the board tariff on other countries, they will eat the cost to remain competitive. That is generally how it works for low barrier to entry goods. Most of what China sells.
For high barrier to entry goods like cars, you set the tariff at a point where they choose to build the product in the US. Thus avoiding the tariff. Why does that happen? Because the US is the biggest and most profitable market for most international goods.
What about strategic things like steel? That will cost a little more (but decrease with energy prices). However, material costs are a very small fraction of the cost of consumer goods. Labor and overhead are much bigger factors. And typically, other countries will not move a strategic good to the US.
What about exports if the other countries do something similar. Well they already are. Tariff targeting will get them to lower their tariffs and make it better for our goods. And a lot of things we export are things that they don’t make or make to our level.
That is the short version.
And that's why if you prefer, for example, Japanese cars you're probably fine in the future as many of the models are already built in the USA as well as some German models are built here as well (I remember years back driving past a Mercedes plant in Mississippi). If a model is really popular in a big market like the USA it's more economical anyway to build it here than to ship them all across the ocean. I remember many years back some old lady who didn't get this trying to shame me for driving a Honda at the time and she was even more indignant when I pointed out that my car was built in Ohio by Americans while her Ford was one of the many models made in Mexico.
