I think most would agree he would have a moral obligation to share such technology/wisdom. More than likely many social problems we have today we already have the means to solving them we're just not using them. Fundamentally, we have the tools neccessary to distribute labor, and fruits of labor in a way that breaks down many damaging situations, but we have structural problems preventing this.Yes?
Would you prefer to be a slave?
From what I understand Rand beleived we OUGHT act toward our own personal wants. If we want to help others we could do that (and we ought do it, according to her, if it helps us in some way)... if we want people to like us then it's okay to lie to them, manipulate them.. or give them the illusion you're being kind, when in reality you only are showing kindness for some personal gain. I think a society could work where everyone is selfish, I just disagree morally with the position. The funniest thing is about the about the philosophy that you Ought to do all things for your own ends... The funny thing and most ironic thing is those who have it can't ever actually be happy. It is a genetically unfullfilling purpose they place on all tasks they do. This is where I'd say Illusions "you're right to use the word hard-wired", it's fairly clear somewhere core to our biology this doesn't work. Even if in theory it could work, in practice it will not. Nessus has run into this problem (even though she's not an objectivist) and many others. Biologically we seek out content outside ourselves.So far you haven't described anything that is counter to what Rand believes should be society's standard operating procedure.
Luckily for me, I don't have this problem, because my philosophy is totally different and I say luckily because it just so happens to be in sync with my biologically human cravings.
