I doubt that American auto makers like Ford are as happy as, say, dairy companies. They’ll see their labor input costs rise while sales to China fall due to price increases. Odd that Ford would be pissed over steel prices since their cash cow is the F-150 and it’s had an all-aluminum body since 2015. The new deal should also bolster labor and labor unions, a key Trump campaign promise. Probably not going to make Ford happy, either.
Tech companies will benefit in the long run from strengthened US patents and trademarks, and in the short run from a bump in the duty-free limit of goods taken into Canada and Mexico. Strengthening patents and trademarks is a huge benefit to tech.
ETA: I see that British Columbia has also been opened up to American wine. That’s probably gong to make Napa valley and rural parts of California, Oregon, Washington, New York, New Mexico, and Virginia very happy.
