Much of this is about the dirty part of the supply chain. Take solar panels, china makes like ~90% of the worlds supply, yes there is the high end research, but

Much of this is about the dirty part of the supply chain. Take solar panels, china makes like ~90% of the worlds supply, yes there is the high end research, but then there is the poly silicon mining and refining/ingots, wafer, cells, and modules. You can’t just reshore some it - you have to do all of it, otherwise it doesn’t make a ton of sense, and that means mines and refineries which we’ve rightly or wrongly stopped building here in the US.
