If a country is doing price dumping, there's even legal ways of protecting these sectors, by applying to WTO (but the U.S basically killed the WTO). But even if the U.S don't trust the WTO, they could apply antidumping tariffs to these specific sectors (like the 100% tariffs Biden administration did to EVs).
U.S is not doing this right now, it's protecting "all sectors" of the economy. There's no other reasonable developed country with a 29% tariff.

You'll also notice that most developed or growing economics have low tariffs...
On specific industries they want to protect. Not completely across the board.
If you want to use that for argument, you should include US sales taxes in the calculation too. Which could be fair, I guess.
Also, every person in the US can import goods to a value of $800 per day without having to pay any duties. In Europe you have much less generous rules, and sometimes the limit is €0.
And as long as taxes on labour exist, I don't think anybody can complain about other types of taxes. Any negative economic impact that tariffs or any other taxes have are doubly worse from taxes on labour.
I've been seeing your perspective a lot lately online - that this will somehow cancel income tax. Where is that coming from? I haven't heard a single thing about that from the administration. Where is the basis?
If what you say is true, tarrifs should not exist in any country. And yet, most countries are using tarrifs.
What if a particular country is using dumping and sell at prices so low, it will kill a particular industry? And after they kill it, they start jacking prices at unseen levels and you will have to pay because you don't have a choice?
