The other really important point I want to make on this graph is that, if you look at the bottom, Sweden and Japan, they're very different countries in all sorts of ways. The position of women, how closely they keep to the nuclear family, are on opposite ends of the poles in terms of the rich developed world. But another really important difference is how they get their greater equality. Sweden has huge differences in earnings, and it narrows the gap through taxation, general welfare state, generous benefits and so on. Japan is rather different though. It starts off with much smaller differences in earnings before tax. It has lower taxes. It has a smaller welfare state. And in our analysis of the American states, we find rather the same contrast. There are some states that do well through redistribution, some states that do well because they have smaller income differences before tax. So we conclude that it doesn't much matter how you get your greater equality, as long as you get there somehow.
