Hmmm???
The point of tariffs is to make imports more expensive thereby reducing the demand for imports. The importer pays the import tariff/fee (essentially a tax by another name) and passes the cost onto the customer resulting in higher consumer cost. By reducing the demand for imports, the result is a higher demand for locally produce products since they become more competitive. . . assuming local products might be cheaper than the imports with the added tariff cost.
This is a big issue for small businesses, like Paul's, that are already on a small profit margin and have no way to offset the increase in their costs and keep their product affordable.

I guess we'll be seeing where this all goes for him.
Tariffs do provide revenue to the government of the importer. But will that revenue be used to help those small businesses?
