In addition to being kinder and gentler than we think, the United States is much less fair. This is beautiful, disturbing information. The great news is that there is grand wealth here waiting to be usefully deployed. The Gini index (no relation to Al) measures national wealth distribution. By the Gini scale there are lots of models to study of countries whose national wealth is more smartly and effectively spent. The US could join the list. We could lead the world in fairness!
