Meanwhile back at the ranch, no one can explain how tariffs address the core issues of why businesses are fleeing this country.
The core reason businesses are fleeing this country is that the costs of doing business here is grater than the cost of doing business overseas and importing. One of those costs is labor; American workers have been brought up to expect a wage that will allow them a middle class lifestyle, and an early and comfortable retirement, which foreign workers do not. Another cost is the expense of meeting safety and environment regulations, which (some) foreign governments do not impose.
Tariffs address these issues by increasing the costs of doing business overseas and then importing the products to the US for sale. To be sure, the end consumer eventually pays the increased cost, but the end consumers, as taxpayers, also pay the costs, not listed on the price tags, of ‘exporting jobs’ and importing goods: unemployment, increased need for public support of the displaced workers, decreased tax revenues for state and local jurisdictions, etc. However, if the cost of closing down domestic business and outsourcing to foreign subsidiaries is high enough, the firms will stay here. But the end consumers pays for it, one way or another.
