tariffs are in truth of little importance in the kind of trade the us does with either the eu or japan. the japanese will just do everything in the us to begin with, where there are no tariffs. the eu exports items like drugs, luxury cars and specialty foods. are you going to buy the local cheese or wine instead due to the 15% markup, if you want the import from france, which you were going to pay twice as much for anyways? are you going to buy a different lifesaving medication? or a bmw copy?
these are the kinds of goods i've been telling canada to tax, and that's what a tariff is here, in context. imports into the united states from europe have low elasticity in demand, so you can tax them. that's actually smart. it doesn't matter if it's 15 or 20 or 30, it's the same demand curve. people will just shrug and pay.
so, i don't even care about this. i'm more concerned about these investment agreements.
