Economy

1) As you state, the revenue is a tax on Americans. I get a sense now from economists and business analysts that about 80% of the tax will be paid by consumers and the other 20% will be split between exporting companies and importing companies.

Further, as international trade inevitably declines under tariff regimes, tariff tax revenue declines.

2) The social goal, as stated, is onshoring of manufacturing, supposedly for jobs. But Lutnick and others have spoken the quiet part outloud a couple of times that robots will get most of the jobs. So the onshoring for jobs is a lie.

3) Supposedly national security is a motivation so that in times of war the US could produce onshore all it needs for a war effort. Thing is that when an economy shifts to a war effort, consumer goods dry up as production shifts. So one doesn't need a massive industrial base to produce what is needed because even a big base, merely big as the US base, can carry the load. Some strategic areas like rare earth magnets do need onshoring, but those are few and far between.
