We might take a page from John Rawls here: https://en.wikipedia.org/wiki/Veil_of_ignorance https://en.wikipedia.org/wiki/Veil_of_ignorance If everyone were behind a veil of ignorance and had to craft a just tax system without knowing whether they, themselves, would end up as poor or rich in such a system, would they nevertheless agree that those who are extreme outliers in terms of their wealth should contribute more? My guess is that this proposal probably passes the veil of ignorance test. Which is not to say that it couldn't have its downsides, or that reasonable people couldn't offer very good objections to it. But by definition, a question of higher taxes on a tiny portion of extremely wealthy individuals is going to involve putting the question to people who, with rare exception, aren't going to be subject to the tax. But that doesn't necessarily mean their decision is unfair.
