This flies in the face of the more than one person I know personally that tried to take stranded US based manufacturing assets and turn them into something with a future. So far, no luck
I still believe there is upside in this space over the next decade or so but I haven't met anyone who's won in a repeatable way yet.
A sane application of protectionism would be more like Britain in 1800 - Importing a ton of raw materials from overseas (e.g. cotton), and selling them the products made from them (textiles). Tariff Chinese washing machines but not foreign steel, magnets, and wire that we could use to make our own.
Aluminum, iron, and coal mining jobs, etc, are not what I want to add. Car factories on the other hand, sure. So far, the tariffs have been more likely to hurt those factories than help them.
