Yeah, I know it sounds like a goal post movement, but I didn’t make the original claim, and in fact thought the original claim was oversimplified, but that there was a truth to it. I think that in order to best illustrate that truth, “billion” had to be removed as it was a red herring.
And yeah the first half of it sounds like I’m setting a variable X, where X makes me right, but the fact that such an X exists is the point I’m making. If you agree then we’re on the same page. The alternate claim would be that it’s possible in our late stage capitalist society to be the richest person using purely ethical, non-exploitative means, which I don’t believe is possible. And for a value of X=a billion, I think it’s just very unlikely.
