I'll throw in my 2 cents on tariffs. Tariffs are actually a good thing when applied in an intelligent and logical way, as was done by Britain during the industrial revolution and the US from the mid 1800s to around 1950 or so. When done properly it encourages domestic investment in production & technology, but there are certain conditions which have to be met to make things work.
The first condition is we need to have existing production in our country for the stuff were tariffing. For example, the US has no domestic production of titanium or any sources of it on our land so putting tariffs on Chinese & Russian titanium isn't going to create any jobs or production in the US, all it'll do is make everything more expensive for our aerospace companies. Tariffs on machine tools on the other hand would make sense since US has several domestic manufacturers but they can't compete against the cheap stuff from China. What we could do in that case is put a small 5% tariff on machine tools from friendly nations such as Japan & Germany while hitting China with 100% tariff on their tools. At the same time we offer some buy American subsidies to encourage domestic investment & production of machine tools, over time, this will increase domestic production and bring costs down while creating well paying jobs for Americans.
Next, we have to decide which parts of our economy are worth investing in and which parts can be left to other nations. For instance, does it make sense to make toilet brushes in the US or is it better to let China make it for cheap and import it for a dollar? For some things it'll be obvious, anything related to the defence industry should be 100% domestic from start to finish, aerospace is the same, but for stuff like computers or consumer electronics there's an argument to be made either way.
We then go through every sector of our economy like this and apply the tariffs accordingly against various nations. This was an important part of how Britain and the US became industrial superpowers, both nations figured out what was important to their industry & economies and applied tariffs accordingly to encourage investment and improve production & quality. That's the right way to do it. Trump's throwing shit at a wall tariffs are going to be a failure since they don't take any of the above into account.
