On the other hand, think of the percentage of time students spend being taught and trying to learn (if only until after the exam) material they'll never use: the intricacies of Shakespeare, geometric proofs, balancing chemical equations
, the causes of the Peloponnesian Wars, years of Spanish (yet ending up unable to speak more than restaurant Spanish.) And the cost - not just the hundreds of thousands of dollars for college and hundreds of thousands more for graduate school but the opportunity cost: what you could have been earning and learning of real-world value if you weren't stuck behind a desk listening to Professor Hasenpfeffer.
