Some of that surprised me as well. But... these sorts of micro-rankings of countries that all have similar "operating systems" are not very useful. The real lesson here is that OECD countries which by and large practice liberal democracy and free markets are tightly clustered on most quality of life measurements, while countries that don't tend to cluster lower down. This is true of countries with vastly different cultural legacies, and even countries like Japan that has liberal demoracy successfully forced on them at gun point. It makes you wonder just what Buffet thinks he's talking about. I doubt he knows.
