Oh, he talked about it, a lot, but the only effort I ever noticed was, as you say, tariffs. Tariffs seems punitive, and when there's no other option to purchase, you import and pay the tariff anyway.

The Biden push for requiring federal purchases to have more 'made in USA' components seems a combination of stupidly simple, long overdue, and easy to understand. Govt requiring more stuff made in the US - and giving some tax cuts to help spur it - seems like it's a basic way to ignite manufacturing stateside.
