Different cultures must adopt different means of survival. Western Europeans and Americans receive TFR boosts from immigration and from being relatively less academically oriented. Most people in the West take more pride in their athleticism and early romantic experiences than they do academic prestige or career advancement. The same factors that make them less competitive vs. East Asians in school and work, also make them more fertile.
Contemporary Western societal structures and economic policies will not work for East Asians the way it does for the West - indeed, it is down right toxic, as we have seen the catastrophic effects on East Asian TFR. East Asians are more collectivist, competitive, and prone to delaying gratification for future rewards - a consequence of East Asia's intensive agricultural civilization, and in contrast to the nomadic, militaristic Indo-Europeans. Such cultures struggle to maintain TFR in environments where education and career are placed above family.
For East Asians, direct policy support is needed to keep TFR competitive with other cultures. Remember, children are the future of a country, and we should invest in them, the same way we invest in infrastructure and education and health care. What is the benefit of gaining wealth and power, as a nation, if you're going to end up throwing it all away through demographic extinction? It is the duty of every human society to ensure its own reproduction; the selfish, materialistic individualism currently practiced in East Asian countries influenced by the West, simply cannot be allowed to continue.
