Ea appears to primarily be a post hoc rationalization for someone's unhinged drive for money and power. A way for people who see themselves as good, but act according to a different set of principles, to launder their consciousness through a compelling sounding framework. Now, this isn't to say that all EA practicioners are like this, or that it's bad (I think doing some good is better than doing none, if we can quantify good...), or even that there's a better alternative in the system that we live in. But the whole thing just feels inauthentic and handwaves externalities in a way that always felt uncomfortable. So I'd hardly say EA has "proved" anything.
