Deirdre McCloskey makes an excellent case for an idea that should be widely known, but, sadly, isn't.
A practical objection to focusing on economic equality is that we cannot actually achieve it, not in a big society, not in a just and sensible way. Dividing up a pizza among friends can be done equitably, to be sure. But equality beyond the basics in consumption and in political rights isn’t possible in a specialized and dynamic economy. Cutting down the tall poppies uses violence for the cut. And you need to know exactly which poppies to cut. Trusting a government of self-interested people to know how to redistribute ethically is naïve.
