Wonder why the culture-rich, wise, eco-friendly cultures of Africa and The Middle East aren't on the list.
Maybe it's racism.
Basically, white Judeo-Christian cultures.
BS!!
Its a much smaller subset of “judea-christian” with other factors being more important. there are no jewish nations, no orthodox nations, and almost no catholic nations.
With the exception of france and singapore, it is strictly protestant nations.
But more importantly, it is nations with strong democracies and a large amount of natural resources per capita and a low degree of corruption and a strong private sector economy that does not rely on tourism or entertainment. It is nations with well developed agriculture, mining, manufacturing, and finance...and good laws applied and enforced with a good degree of fairness.
