Even so, it seems to be conventional wisdom that Trump did well in the first 15 minutes. And I guess he did if you are impressed by someone talking loudly and confidently about a subject he really doesn’t understand. But really: Trump on trade was ignorance all the way.

There were specifics: China is “devaluing” (not so — it was holding down the yuan five years ago, but these days it’s intervening to keep the yuan up, not down.) There was this, on Mexico:

Let me give you the example of Mexico. They have a VAT tax. We’re on a different system. When we sell into Mexico, there’s a tax. When they sell in — automatic, 16 percent, approximately. When they sell into us, there’s no tax. It’s a defective agreement. It’s been defective for a long time, many years, but the politicians haven’t done anything about it.

Gah. A VAT is basically a sales tax. It is levied on both domestic and imported goods, so that it doesn’t protect against imports — which is why it’s allowed under international trade rules, and not considered a protectionist trade policy. I get that Trump is not an economist — hoo boy, is he not an economist — but this is one of his signature issues, so you might have expected him to learn a few facts.
