>When questioned about the specifics of his plan, and if he was aware of its pitfalls, Trump seemed ignorant of basic economic principles, insisting that other countries, not American consumers, would pay for the tariffs.

>Micklethwait tried to explain the actual impact. “Three-trillion worth of imports and you will add tariffs to every single one of them, and push up the cost for all of these people to buy foreign goods,” he said. “That is just simple mathematics.”

>“That will take many, many, many years,” Micklethwait said, to which Trump replied that high enough penalties would make the move immediate as if companies could simply wand wave production plants, orchards, wineries, factories, and the like into existence.
