I did not intend to say this in my post. I said that a billionaire's capacity for harm is greater than that of other people, so it is worse to be a hypocrite. But I also do believe that simply having a billion dollars is unethical as well, or at the very least antisocial.
> Say you’re right, how do we prevent people being billionaires?
This is hard. But I do not believe that "enforcing a policy that prevents billionaires is hard" is a reason for believing that being a billionaire is pro-social behavior. It would be both difficult and probably unwise to create a policy that punished people for cheating on their spouse or (less seriously) flaking on a social engagement without notice. But I think it is thoroughly reasonable to still say that those things are unethical.
I think that the challenges of policy preventing billionaires are largely related to enforcement and management of illiquid assets. I do not think that such a policy would disincentivize entrepreneurs. I believe that few entrepreneurs get into the business for the purpose of becoming a billionaire. Ending up with 900M is not going to cause anybody any tears. And if it is the case that such a policy disincentivizes entrepreneurship, then it sure as hell proves that the claimed incentives like personal satisfaction, self determination, job creation, and providing value to customers are all bullshit.
