> Business majors have had ethics courses for as long as I can imagine

I took a business ethics course in undergrad, and it was surprising how many students advocated all sorts of (to me) aberrant ethical views. (Note I’m pretty traditional, morally speaking. The environment was strongly postmodern, and this was before all the modern insanity about “free speech is bad because some people say bad/offensive things”.)

Not that I minded personally, but it was a strong lesson to me that teaching people categories and how to think won’t give them a desire to respect any particular brand of morality.
