I was at a conference last week and a financial advisor asked me what I thought he should say when a client asked him what was so bad about tariffs.It’s a fair question. Many people who instinctively believe in free trade would still have a hard time in clearly explaining the trouble with tariffs. And since tariffs are likely to be a big issue this week, with the president promising to impose postponed 25% tariffs on Mexico and Canada and a new, second 10% tariff on China as of March 4th, it seems like a good time to review the problem.
