There's also Fischer's historical generalization that periods when the purchasing power of currency is relatively stable have low illegitimacy rate; perhaps they know how to avoid currency depreciation, whether through strict banking regulation or simply letting banks that issue too many notes suffer from runs.

You're assuming that marriage as we understand it in the 1550-2030 period is eternal. Many societies have have far easier divorce arrangements than the modern West. Others have forbidden divorce.

Modern economies seem to reward equality between the sexs. Wealthier cultures tend to have less formal views on marriage and illegitimacy, with South Korea and Japan being the biggest exceptions with the lowest birth rates. So I don't see a long-term movement towards Victorian middle class marriage norms.

Several new contraceptives have come up which don't have the issues of today's contraceptives. So the environmental issues with contraceptives are likely to go away in a decade or two.
