Most Non White cultures (African, Caribbean, Chinese, Indian, Turk, Arab, Armenian, Persian, South American, South East Asian etc) with the exception of some East Asians like modern day Japanese and south korean have tight knit communities and extended families. Kinship, socializing, respect of traditions, ethnic solidarity etc runs deep in these communities/cultures. Their birthrates are high. Their countries don’t need immigrants to increase the population and sustain the economy.
The Eastern European and Mediterranean nations( Italians, poles, Ukrainians, Russians, Czech, Hungarians, Romanians, Spaniards, Greek, Portuguese etc) are the exception in the white European world, they behave more like non whites culturally and socially. Scandinavians and Western Europeans( French, British, Belgians, Germans, Dutch, etc) suffer from loneliness, social atomization and individualism. They see themselves as individuals and not part of a community. They have nuclear families instead of extended large families, which explains their weaker family/social ties. Their birthdates are lower than average. Their countries need immigration to increase their population and for economic purposes.
Most people in north America ( Canada and USA) and australia/new zealand behave more like Western Europeans/scandinavians
