It may increase domestic production for domestic customers, but I think we ran that experiment before. What I found decades ago is that products made domestically, driven by greed, profit seeking, marketing and labor costs were too expensive for your average customer. Tools for example; look at the pricing of simple domestic hand tools, technical and heavy duty. Scopes, meters, soldering tools, socket sets, electronics, schematics and repair manuals, specialty auto tools; there was a time these were too expensive for the average consumer. Sure it created manufacturing, sales and distribution jobs but by lock in - this did not make the technician or the customer wealthy, but it did make the business owner wealthier as they were the moneyed and licensed gatekeepers, charging royally for access. *As a youth I was screwed by electronics manufacturers, car companies for access to semiconductors, schematics, tools, and special tools. I believe that is exactly what China has faced for decades and has been fighting against, at least partially.
