* '''No responsibility''': Historically, marriage directly concerned important questions about inheritance of land and wealth. Today, there is a growing disenfranchised population that has virtually nothing, are in debt and merely rent properties from landlords. This is exaggerated by economic stagnation. Millennials have only a fraction of the worth babyboomers had at the same age.<ref>https://archive.fo/wip/z8CaW</ref> As a result, traditions and adaptations concerning heritage and responsibility lose their meanings.
* '''Environmentalism & pessimism''': Historically, it was rarely ever a question to not have children. Usually, children were needed to maintain land, power and wealthy of the family. Associating something bad with reproduction is highly evolutionary novel.
* '''Late marriage and no enforced monogamy''': The age of marriage is very late in many Western countries because of [[feminism]] and economic stagnation. This means nobody enforces monogamy until the late 20s or early 30s, and the result is a more feral dating landscape that [[life history|r-strategists]] heavily exploit and which does not cater to people who are rather interested in long-term [[relationship]]s.* '''Decline of communities''': Closely related to the decline of religion, enforced monogamy and arranged marriage, communities have suffered in recent years with loneliness rates skyrocketing. Today, the majority of couples meet online, followed by in a bar or at a restaurant, and there has been a strong decline in meeting through friends, family, school, work etc.
