If education boosts income by improving students’ skills, we shouldn’t be puzzled merely by the impractical subjects students have to study. We should be equally puzzled by the eminently practical subjects they don’t have to study. Why don’t educators familiarize students with compensation and job satisfaction in common occupations? Strategies for breaking into various industries? Sectors with rapidly changing employment? Why don’t schools make students spend a full year learning how to write a resume or affect a can-do attitude? Dire sins of omission.
