Here is the tough truth: modern countries have pretty similar family policy profiles. Marriage is weakened everywhere. Most countries allow obscenity and divorce. Contraception is legal, as is abortion in the majority of countries. Many have same-sex marriage and anti-sex discrimination laws. Nearly all have family subsidies of one kind or another, and most subsidize care outside the home.
The differences that do exist do not always support social conservative expectations. What modern country has the lowest out-of-wedlock birth rate? Here’s a hint: it also has no same-sex marriage and arguably the tightest regulation of obscenity. This country has a strong family culture in a sense. But that country is South Korea, which features the world’s lowest birth rate and is the only country where fewer than 50% of adults are married. The institution of marriage is strong in South Korea; it’s just that relatively few enter it. The industrial-scale familial indifference makes South Korea the basement for family life in the modern world.
