Following on my interest in the Open Philanthropy Project, I read an interview with William MacAskill in which he explains what careers to choose to do some good in the world.
Among other things, he explains that becoming an investment banker and donating a sizeable proportion of one’s income is a better investment than working for a charity. I agree in principle, though of course it depends on what kind of a charity one would work in and what position one would hold.
He also has a strong opinion about the potential of Economics PhDs, as opposed to other PhDs.
The interview is an interesting read, though his way of looking at things is almost too utilitarian.
