When the US starts adding 25% tariffs to imported items, who do you think will end up paying that extra tax? The importing companies won't be eating it, they'll be passing it along to US consumers.
Similarly, US goods coming into Canada will now have a 25% counter-vailing duty placed on them, while European and Asian goods don't ... guess what Canadian consumers will buy?
Until the 1980s, tariffs WERE in place in both countries, and multiple economists pointed out how they were stifling trade ...
guess the same hard lessons have to be re-learned again ...
I'm just over the border from Alberta (NW Montana), and as a young man the only duty was on cigarettes, alcohol, and tobacco. I could go across the border with nothing but a MT driver's license. Trade across the border was pretty even except that Yankee bucks were always worth more than Looney bucks. I remember that rather fondly, having had a broad interaction with my Canadian brothers.
There ain't no other that understands the USA like the Canucks. Brothers from another mother. I was reminded of that during the Trucker's Strike.
That there should be offense from either direction in the form of trade restrictions is a damn cryin shame.
