Presentation is key on subjects like Econ that some would just teach as a series of charts, graphs, & formulas. I took micro & macro Econ courses as prerequisites for admission to the MBA program because my bachelors degree was not business. Taking it at night at a small regional university meant the instructor was an adjunct part-timer. He made both of those courses come to life for me & memorable across the past 4 decades. I wouldn’t have traded him for having a full professor at all.
I think the key to teaching is the outlandish example. My students said they wanted to end poverty (which as $9600/family way back when). I told them I could end poverty overnight...it’s easy. They asked me to explain.
I told them all you had to do was gather up everyone who made $9600 or less and shoot them. Their eyes went as big as pie plates! I then asked them: “How long would it take until the person making $9601 started bitching that he was poor?” We then had a meaningful discussion about the distribution of income and how talent is not evenly distributed.
I’ve had more than one student tell me, decades later, they never forgot that discussion.
