Qui docet discit
Academic economists play many roles; researchers, policy advisor, teacher, etc. While each of these roles is important for the career advancement of an economist, the most important role of academic economists is teaching future citizen economists. It is incumbent upon economists qua teacher to prepare them to make sense of the world they will inhabit. We must, therefore, not teach economics, at least at the introductory level, as if it is the first course on the way to a Ph.D., but as if it is the last class the students will ever take in economics. A consistently subjectivist economics is the best way to teach future citizen economists. When students understand economics as something that helps them make sense of the world, rather than a course in applied mathematics, they will be better citizen economists less likely to fall prey to those selling them free lunches.
