In modern societies, the daughters of well-off families often grow up in an environment protected from sexual seduction.
In contrast, girls in poor families, especially when both parents work, are more likely to be sexually active at an earlier age.
Poor societies tend to be more sexually active than rich societies, as typically, rich societies allocate a good part of their resources towards “protecting” young people, especially girls, from sexual initiation.
Rich societies also allocate a good part of their resources to controlling their subjects, so that they do not engage in illicit sexual conduct.
Biology can explain why wealth is sexually counterproductive.
In human evolution, there has always been a trade-off in which females granted sexual access in exchange for protection and material support.
If women are wealthy (including daughters of rich parents), or if societies offer a high degree of protection, then women lack reasons to enter sexual relationships for material benefits, or to have a protector.
Societies of great affluence and societies in which public institutions guarantee safety are unnatural, and thus not supportive of human happiness.
Kreutz Ideology analyzes the evil of wealth and advocates poverty.
The advice of Kreutz Ideology is as reasonable as the recommendation from physicians that people should eat less to avoid obesity, even if they can afford to eat plenty.
