Oh, that's not your fault. I have more than a few threads I'm thinking through
:D
Let's take Jeff Bezos. The man seems to be doing well for himself. I doubt he feels anxiety. He very likely has more good days than bad. While he doesn't follow the model of Epicurean bliss, I doubt that he needs to. He's probably feeling quite dandy.
But his life requires others to suffer, at least in our way of looking at the world: there's no free lunch, and the rich get rich on the backs of the poor.
So he's an example of a man living in equanimity, who doesn't worry -- but because the social system is set up in a way where others must labor for him.
That's hardly fair.
But by a bio-ethics, Bezos is basically a good person. Specifically, Aristotle's bio-ethics would say he's not just a good person, but
the pinnacle of ethics -- and that being good is reserved to those like Bezos who are among the elite. (or, at least, he serves as an example -- due to the nature of ethics, of course we could posit someone else or interpret Aristotle differently, but I'm trying to use a real person due to the concern you brought up about philosopher inventions)
Moore's open question argument still punches because I can ask -- while Jeff Bezos is living a good life, is he good?
Just that the question works is all that matters, from the meta-ethical point. But I can understand that such things are rarified in relation to how one lives their life.
So, from my perspective -- and not because it is true -- I say Jeff Bezos shouldn't be allowed to exist in the first place, that his life is a bad life because it's not fair, even though he's living a naturally happy life (I doubt tranquility is his M.O., which is where the Epicurean would criticize him -- but the Peripatetic could very well say, yes, Bezos is the pinnacle of human goodness, and we are justified in so saying due to our biological nature)
