This is a very interesting thread. Thanks, jyl.
I have always loved economics/finance so a BS in economics was a no-brainer for me. I also decided, since I was interested in politics at the international level, to get a BA in International Studies. I wanted to follow in the foot steps of an older family friend who worked in various countries doing risk analysis (political and monetary) for major banks and investment houses.
Both degrees have served little purpose outside of my personal investments and interests, that is just the way it worked out. The accounting courses, stats, etc. have been put to use but, since I retired from the USN, running small businesses has little to do with macro economics day-to-day
The best courses for life I took in college?
Speech and acting classes. I also benefited from tutoring other students and working through college. Getting in front of people, learning the ability to communicate well and impromptu is a critical attribute for growth and opportunity regardless of the degree.
My MS in Systems Engineering has been incredibly useful, still is.
