Here's my .02 cents from a manufacturing perspective, considering I own a machine shop...
The tariffs will have a positive effect on manufacturing in the US. I think everything should have been put in effect in a "ramp-up" schedule instead all at one time, but that's just me.
Since the 1980's the US has had a steady decline in manufacturing. Manufacturing jobs affect the economy in a way that other jobs do not. Every one job in direct manufacturing creates 2-2.5 jobs downstream. The US has let manufacturing dwindle to record lows, as more and more companies went to offshore production.
The tariffs will cause a push for more manufacturing in the US... Which is a good thing, but the US has shit all over manufacturing for so long that it won't be able to support a large increase. Our local trade schools used to graduate 20-30 people thru the first year of machinists trade school, and 15-20 of the second year. This year it looks to be 8 in the first year, and 3 in the second year.
Companies will scramble to move production to the US... but there's a huge lack of skilled labor to support it.
