I have taught Intro Economics maybe 30 times in total. (I started very young).
Forget about the A students, because there aren't many of them. (We don't all have massive grade inflation.) Think about the C students. And forget about the Economics majors, because other people will teach them after you. Think about the students who will only take this one course in economics. And think about what they will remember, not for the final exam, but 10 or 20 years after you have taught them. What will they remember from intro macro, if they remember anything at all? Not much.The best you can hope for is a crude and fuzzy caricature.
