If you want to be first with a provocative new viewpoint go to the Becker-Posner blog on why increasing inequality is a good thing in the US (and, following Andrew Leigh’s valuable work, presumably Australian) economy because it correctly signals the increased value of human capital. Its a variant on the response that ‘increasing gaps’ are a good idea. It sets good incentives in place.
I will quietly anticipate the predictable social democratic response – that earnings are much more than a market signal – and then enter the action. Becker has a point but this thesis will drive some to distraction.
