Why is the U.S.’s 1 percent so much richer than everywhere else?: He’s right, at least in saying that public policy is unlikely to be determined by conclusive economic evidence. Both sides have built cases around different metrics, and deride the other side’s methodology as inadequate or incomplete (they’re also not mutually exclusive–both sides are probably a little bit right). But now that we’ve recognized that inequality is real and getting worse, it’s better to have a debate about what to do about it with more information rather than less.
