"Montaigne also detected the agency problem, or why the last thing a doctor needs is for you to be healthy: "No doctor derives pleasure from the health of his friends, wrote the ancient Greek satirist, no soldier from the peace of his city, etc." (Nul medecin ne prent plaisir a la sante de ses amis mesmes, dit l'ancien Comique Grec, ny soldat a la paix de sa ville: ainsi du reste.)"
