Let's say I invent a hyper-efficient, clean, alternative energy source that averts climate change, makes cheap energy universally available and stops a lot of the causes of war. Would me also becoming the richest man on earth as a result matter to you? Would it diminish the value of what I would contribute? And if so, ask yourself why that should matter at all? This isn't some Rand Objectivist thing. I just don't understand why we use words like charity and philanthropy that tie the outcome/value of something in the world to the self-sacrifice of the outcome's author. It doesn't seem all that relevant to most discussions about the value of a thing.
