And what did you gain exactly?

Tax revenue. The nation is tens of trillions in debt with a multi-trillion per year deficit. Tariffs are proportional to spending, and encourage domestic production and security.

There have been several favorable trade deals as well as several announcements for new production facilities in the US... this may cost more than imports, but there's something to be said for domestic security in terms of access, especially in the likes of a global pandemic or war.

I'm not suggesting it's a perfect solution, or situation, only in that it isn't exactly an idea completely without merit and just blindly applied at random.

You're description matches a well planned and communicated slow increase of tariffs targeting specific products or industries so companies have time to adjust (newsflash, US was already doing this). Trump used blanket tariffs as a hammer to extort other countries, but its not like we want to buy your shitty cars anyway. Most of these facilities already existed or were planned. hint: most foreign brands were building their cars in US already.

If the economy is doing so well because of these tariffs why are they hiding numbers?

Its not even the first time US tried tariffs like these, it didn't go well then but Trump talks about like it was a golden age.

The US seemed to get through the industrial revolution mostly with tariffs over income tax revenue which was extremely limited early after enacted.

And you believe the world is similar to what it was back then? Are you mainlining fox news?

I think that humanity hasn't changed as much as maybe you give it credit for as a whole and that most human behaviors are somewhat consistent. I do think that taxes on actions as part of trade is better than taxes on income. I also think that taxes that are somewhat protectionist are better than "free trade" against nations that don't have similar quality of life, laws regarding labor, or free trade themselves.

The portions regarding trade are borne out by the VAT systems in place throughout EU and UK. The fact that tariffs exist in pretty much every nation of the world bears out their utility. The reason that most people are even arguing against it is that its being championed by Trump, who is admittedly a bombastic personality.

My opinions on tariffs long predates Trump. I have similar opinions against property taxes against individual ownership as well. I don't think that you should be at risk of losing personal property for the simple fact that you survived another year.
