This document discusses how careers in finance can be ethical by enabling graduates to save many lives through donations. It argues against the view that charity careers are most ethical, noting one can indirectly benefit many more people through a high-paying city career. For example, an altruistic banker earning £400k could fund 10 doctors saving 100 lives per week, more than one doctor alone. With the right career choices and donations, one could save thousands or even millions of lives while still living comfortably. The key is choosing impactful work and causes based on cost-effectiveness research rather than intuition.
