Looking into a college textbook as an adult is a shock (and a vivid reminder of why we were so glad to get out of school). The prose style is at once puerile and impenetrable, Goodnight Moon rewritten by Henry James. The tone varies from condescension worthy of a presidential press conference to sly chumminess worthy of the current president. The professorial wit is duller than the professorial dicta, and these are dulled to unbearable numbness by the need to exhibit professorial self-importance. No idea, however simple—“When there's more of something, it costs less”—can be expressed without rendering it onto a madras sport coat of a graph and translating it into a rebus puzzle full of peculiar signs and notations. Otherwise the science of economics wouldn't seem as profound to outsiders as organic chemistry does.
