After WWII Europeans decided to build an egalitarian society and focus on wealth creation, peace and cooperation. Pre WWII they were just too much for the world, as the concentration of powers, including clash of ideologies and need of survival, led to ultra competitive environment at a cost of aforementioned values. They were a leading edge once, due to continental race of industrialization. Because of this structure basically 80% of the world was under European rule. They just prefer watching from the backstage now. Let’s pray this continues.
