I don’t dismiss the value of a few business courses in accounting, corporate finance, investments, entrepreneurship, or even in option/derivative theory or risk management, etc. Perhaps even for all students (like personal finance which is now a standard course in many high schools). But I just think its value is too limited to be worth spending four years of your life. There’s also too much groupthink in business schools that there’re peoples like James Simons who don’t want to hire any of them.
