Why Trump Hearts Tariffs

It isn’t just that he’s a mercantilist.  They give him arbitrary power over the entire world.  Everyone has to come to his door and suck up to him to avoid being a victim.  He can make or break fortunes at a whim just by citing to “national security”.  He can create a new cliffhanger every day.

Does anyone out there think he would give up that power voluntarily?
