I’m sure you’ve heard the cliché about the missionary who “went out to do good and did well.” I know someone who worked with food aid for a long time in a certain country. They parlayed that into a high-paying consulting job in Washington. So basically they profited from their “selflessness.” On the other hand, someone had to do the work, and they were good at it.
Leadership in general is something I’ve thought about for, oh, 50+ years. My own opinion is that ANY leader has to have a rather exaggerated ego to function as a leader. You don’t want someone who always says, “Gee, I dunno, what do you want to do, Eddie?” On the other hand, you don’t want to be someone (DJT comes to mind) who always thinks he’s the smartest person in the room.
The same with philanthropy. By the very nature of the work, you are saying “I am better (in some way–financially, physically, etc.) than you. So I’ll do you a favor and help you.” I’m sure there have been some very humble people who have “helped” other people, but I suspect they are very rare. That’s why when one appears he/she is made a saint or the subject of a biography or movie.
But in the end, their motivation is secondary. If they can help someone, let them help someone. If this makes them feel better than everyone else, that’s their problem. Maybe they’ll change, although I wouldn’t hold my breath.
