Is economic inequality around the world getting better or worse?

CRITICS of capitalism are convinced that the gap between rich and poor is widening across the world. For them, the claim amounts almost to an article of faith: worsening inequality is a sure sign of the moral bankruptcy of “the system”. Whether rising inequality should in fact be seen as condemning capitalism in this way is a question worth addressing in its own right. There are reasons to doubt it. But it would also be interesting to know the answer to the narrow factual question. Is the familiar claim that capitalism makes global inequality worse actually true?
