I think Africans are more optimistic than Swedes. Having said that, I'll comment on Follow Me Here and the Inglehart-Welzel Cultural Map of the World. Essentially, the more "enlightenment 2.0" you are, the more you move to the top right of the chart.
The blessed nations include Norway, Denmark, the Netherlands and, way out there at tip-top, Sweden. Japan and New Zealand approach from different directions, the US has a ways to move.
I'd love to see a dynamic model of this chart, showing the movement of nations over the past 30 years. Zimbabwe, by the way, now owns the bottom left.
