According to Wikipedia,
A developed country (or industrialized country, high-income country, more economically developed country (MEDC)) is a sovereign state that has a high quality of life, developed economy, and advanced technological infrastructure relative to other less industrialized nations.
There are only a handful of nations in the world that are Developed. Most of the countries are in Europe, or the countries where the majority of the population are the direct descendants of white Europeans.
the ratio of developed countries in Asia is 5:48. On the other hand, the ratio of developed countries in Europe is much higher 26:44.
If we consider four Asian Tigers + Japan as outliers, there are almost no countries left outside the European descent that reached developed status.
What is the core (low level) reason behind this?
