Regarding your question #1,
The increase in the cost of living will reflect the cost of regulation in the US, which presently is not borne by the US consumer, who can buy goods from China that have no labor laws or environmental regulations that are not part of the cost of production. The proper response is “can we afford these regulations”, not “can we afford this tariff”.
Regarding Question Two:
There will be tremendous political pressure to NOT remove trade barriers, in the event that trade becomes bilaterally free. No question that the basis for cost of manufactured goods must include the cost of regulation, whether goods are imported or not. The proper response is “is the regulation worth it”.
Thank you. Sounds fully reasonable and to the point. Now need some time to ponder and think that through. LOL
