A brief discussion........................

............on tariffs and the "least harm principle".   Wee excerpt here:

I first formulated the principle my senior year at Swarthmore Colleg, which was when the Lettuce Boycott became the cause du jour on campus. Some of my fellow econ majors wanted to raise objections to the left’s insistence that the dining hall only serve union-picked lettuce. I suggested that we should not bother, since there were so many bigger issues around. “It’s the least significant issue they could have chosen. We should be happy that this is what they are focused on. Call it the least-harm principle of knee-jerk liberalism.”
