MIT's Technology Review ran an article on inequality, where they argue that a) it is bad, and b) it is technologically driven, in that it raises some people's income and wealth more than others. I see a tension in these. Suppose I could wave a magic wand, and double the income of everyone in the bottom half, and triple it for everyone in the top half. This would benefit everybody, at the cost of increasing inequality. Would this not be a good thing?
