Want to make Trump understand how Tarrifs work?  He just provided the opportunity.

On the heels of Trump’s 50%tarrif on copper, my suggestion is that any Canadian who still has a jar full of pennies sends them to the White House in care of Donald J Trump and he would have to pay the tarrif. Maybe he would understand how tarrifs work, maybe not, but it would be hilarious to see the look on his face. I invite any country that still has copper coins to do the same, especially if, like Canada, those coins are not in circulation anymore.
