Go back to my comment further up. When has he ever publicly or privately demonstrated that he understands economics? He repeatedly insists that exporters pay tariffs. He says a trade deficit means we're being robbed. His list of misapprehensions on basic ideas is very long. Absent evidence to the contrary, one can only conclude he knows nothing about economics. Maybe he studied it 50 years ago and maybe he didn't. He has not demonstrated an iota of fluency since entering politics.
