As I commented yesterday, there's a playbook for reshoring that's being totally ignored:
First you invite industry to reshore via subsidies and preferential access to government contracts. If necessary, the government must directly invest in new firms. (They already do this in a very small way with In-Q-Tel and others, so it's not totally beyond the pale. For a time there was even a US Army VC firm.) If you talk to a Chinese factory owner or mine boss, many of them will tell you that they got their start with a >$2M direct investment from their government.
Second you gradually tighten the screws on foreign finished products, not industrial inputs like metals, plastics, ores, etc.
Third you streamline export paperwork requirements and relax things like ITAR.
Then, when that's all humming along and the factories are working, you can launch blanket tariffs to protect your nascent industries, if need be. But you must exempt necessary industrial inputs from tariffs.
It's possible that personnel problems can, to some extent, be solved with automation.
But, anyway, the playbook's being torn up and read backwards, so it's all moot. We're just going to have to ride the tiger and see what the world looks like in a few months.
