You are speaking with great confidence about a thing I know a great deal about.
1) civilizational and cultural differences are in fact due to neotenic evolution, demographic composition (genetic distribution), climate, available resources, number of competitors, difference in advancement of competitors, the means of formation of the military caste, and the subsequent relation between the upper(martial) and lower(agrarian) classes.
2) Subsequently there are three means of human coercion. There is one institution that evolves to specialize in each means of coercion. the sequence of institutional formation determines the priority of institutions. The surviving civilizations differ largely in the order of the evolution of institutions.
3) Subsequently cultures develop a group evolutionary strategy, a metaphysical set of presumptions about the world because of that strategy, a set of myths, histories, traditions, values, and a ‘custom’ means of argument (philosophy etc) with a custom method of logic (better or worse) to defend it, and a vast set of habits for the intergenerational transmission of all of the above.
4) As you would suspect, norms, traditions, values, rituals, and institutions reflect the average of the demographic distribution. Thus African four family systems, semitic superstition and religion, hindu ‘culture as religion substitute’, sinic Confucianism et al, and western law and philosophy. This is because each generation (race) of man as it migrated from the East Afircan rift valley, speciated by a half to a full standard deviation in IQ (neotenic evolution) producing different class sizes, and difficulty in suppressing the lower classes in the absence of cold weather, proximity living, and the stresses of farming.
5) If you mean people can’t integrate, the Irish who were considered equal to Africans as late as the. mid 19th have integrated, and so have (mostly) the germanic Italians. Any individual who is of middle class or higher who attempts to integrate appears to be capable of it over three generations. If you mean people from sub 90IQ populations who are least adaptable, and have the most entrenched culture, especially religion, cannot seem to integrate successfully unless deprived of their communities so that they must, then that is correct. If you mean that people with IQ’s below the threshold of industrial society (about 85) can’t ever integrate because they lack the agency and competency to adopt the high stress of ‘whiteness’, then that’s true.
6) But it’s not that people can’t integrate. it’s that it’s harder for some and easier for others, and when people move en masse they can bring their culture with them. And without suppression of that culture and integration into ours they remain a costly problem that degrades social trust and limit rule of law, high-trust commons, and participatory government. Then that’s true. In other words, 140IQ Nigerian or Ghanian businessmen, or Egyptian engineers, or south pacific nurses, all of whom are hyper successful minorities fit in better than south eastern european Muslim whites.
Fixing our culture is easy.
Fixing our policies is easy.
Fixing our demographics is easy.
I’ve done the work reforming law, constitution, and policy.
The problem is getting it implemented.
That’s not going to happen without “showing up in numbers and demanding it.”
The founders told us how.
And that’s the only way it’s going to happen.
