Tariffs are the only hope to rebuild American industry.. and Canadian. Anything that impugns the totally discredited promises of Free Trade as producing equitably shared economic growth is a good thing.
In the 5 decades of Free Trade the West has seen deindustrialization, polarization of wealth, the decimation of the middle class, and all of the social disintegration associated with encroaching impoverishment.
Tariffs are an essential device to fight economic and cultural disintegration. Borders mean something. It's no crime to apply one aspect of economic sovereignty to the related one of cultural sovereignty in immigration by using tariffs for the commonweal.
