I saw that before, I find it hilarious and outright bizarre for the epitome of killer capitalism to stand there and talk about income inequality. Outright ridiculous. I love him for his trading acumen and insight but I think he and his kind should really shut up about getting things right in regards to anything social or in regards to inequalities in this world. Even a little soul self-massaging by donating a few bucks to needy causes or showing up every now and then at some fund raisers or other events does not change one's real convictions. If he had a true change of heart he would be pledging most of his wealth to worthy causes such as many billionaires and multi millionaires have done. But living a life based on pure greed and a gross disregard for anyone around him/her in my book disqualifies to ever again open the mouth in public domain about social inequalities.
Again, he can do with his money as pleases him, if he wants to invest it for a good cause its fine, but appearing on TED and pretending as if he ever cared about income inequality is outright bizarre. Its like "hey, capitalism has treated me very well, I immensely profited from this system, I benefited from a 'laser sharp focus on short-term profits and corporate greed' and I pretty much fucked everyone in the ass that presented themselves before me, but hey, I cashed out, let's invite China now and teach us how we can all become good communist comrades and love each other".
