The Pseudo-Scientific Attack on Civilization.

The curse of postmodern pseudoscience in most of the other answers. Postmodernism like Marxism was designed, like Abrahamic Religions, as an attack on European Peoples (civilization), to eradicate our civlization in the modern world just as Abrahamic religion was used to eradicate the five great civilizations of the ancient world: Roman New Europe), Byzantine (old europe), Anatolian, Persian (Iranic), Egyptian, and North African. All those civilizations were destroyed by the last attempt at cultural destruction.

Why? Marxism/Postmodernism in the modern world, and Abrahamic Religion in the ancient world foster dysgenic rapid reproduction of the underclasses reversing genetic domestication under small farm mixed agrarianism, effectively weaponizing reproduction and ignorance and superstition against civilization.

There are reasons that the Han, Koreans,Japanese and Europeans succeeded and other civilizations failed to maintain rates of innovation. The reason is that the Han, Koreans and Japanese remained insular and homogeneous, and whites succeed as long as they also remain homogeneous and practice eugenic reproduction through manorialism (meritocracy).

The rest of the world did the opposite and the sizes of their underclasses pose such a burden that they cannot produce sufficient middle and upper classes to produce high trust commercially successful political orders.
