You sound predictably bitter and surprisingly uninformed
Nope. Just involved in manufacturing and contracting all my life. I know exactly what it takes to build a business, to build a supply chain, and how to successfully compete in a repetitive construction and manufacturing market.
The problems in American supply are endemic, and have not been fixed... Paramount among them the high cost and low quality of American labor. Then there's JIT thinking caused by taxing inventory, which means there is no way to create a substantial inventory buffer. Then there's EPA and OSHA regulations that create impossible barriers. And that's just off the top of my head.
Fixing American business is going to take years and years. Decades of government getting the hell out of the way and making a place that is good for business. Not a single presidential term.
And it's gonna take fixing that FIRST. Because no business is going to want to be forced to play here. And the minute they can, they will go right back to wherever favors them.
That all means Congress. Ratified and written in law. That is what supplies a stable and ongoing change. Tumpy can write EOs till the cows come home. Folks will figure out another way to make money without the US and wait for fair weather (four years from now).
That means shortages here, when Asian companies can't make money at it, so stop supply...
Or more cost as Asian companies pass costs on to the American People...
Because there is no American alternative.
Different story if you want to fire up an American industry and impose a tariff to protect that industry while it is young... Give it room to grow.
But if you think a tariff to protect the fat asses in Detroit and the fat asses in the labor unions - If you think that's a good thing, you're in for a real surprise.
FAFO. Here we go.
