I'm not in the US, but (generally speaking) I actually like the idea of tariffs. The problem with complete freedom of capital to move around the world is that there is not the same freedom of movement for labour - and what's more, there never will be, because it isn't only laws that keep people in place, but also emotional ties to their homes and families. Some people are just less willing to move than others.
Freedom of capital without freedom of labour results in most of the capital moving gradually towards places that are friendlier to large business, leaving less jobs for the people still in the old place, who mostly don't want to move to the place where the new factory will be. And this results in a race to the bottom for labour regulations as places try to attract big business back to their area.
A sensible, non-extreme implementation of tariffs or some other kind of barrier to foreign trade means that certain home industries can be protected, and that the jobs needed for providing that industry to country X will mostly be located in country X. The best industries to put the tariffs in place for would be ones for which the country has high demand for, and is capable of meeting that demand itself resource-wise. That ensures the country stays relatively self-sufficient at meeting its high demand, which helps if there's a war or something that interferes with global trade routes. The best industries to have no tariffs for would be relatively exotic goods that wouldn't be commonly available in country X, and country X can then provide in return things which are commonly available there but not in country Y.
And if the tariff causes price increases which reduce demand, well, then, maybe it was consumerism causing people to buy that much of it in the first place. There will still be more jobs in the country than there was, because all the suppliers who were able to supply it more cheaply were taking advantage of cheaper foreign labour, so if there's any demand at all, there will need to be at least 1 place making it in the country if demand is going to be met. If it turns out demand drops to zero because of price increases, then the item was probably completely unnecessary to start with.
The alternative to putting up trade barriers to protect home industries (which will also become necessary in the case of overwhelming automation reducing the number of jobs, if no laws are put in place to encourage employing people instead of robots) is to provide some kind of basic citizen's income, because otherwise you end up with a disgruntled working class who can't find the jobs they need, and that's how you end up with political unrest.
