This is a simple essay. It raises a familiar question about equality, adduces a very small amount of empirical evidence about the social consequences of equality as distinct from prosperity, and broods on the difficulty of providing a really persuasive answer to the question raised. I begin with the view that there simply cannot be anything intrinsically wrong with inequality, move on to the view that there are extrinsic reasons for anxiety, dividing these into conceptual and empirical reasons, though without any great commitment to the clarity of that distinction in this context, and end with some reflections on recent social and political theory. The essay thus begins with what I hope are clear and (what I am sure are) very simple thoughts, before muddying the water pretty thoroughly thereafter.
