It actually gets significantly worse when you consider the current social demographic trends.
Single mother households are quickly becoming the norm in many Western nations, many young men are increasingly dropping out of society and taking the stay at home neet path, and the amount of young people who are sexually, and even socially, active has been dropping like a fucking rock the past five or so years.
If this continues there's going to be a sizeable demographic of late Gen-Z/I-Gen men who, as a result of the above, are going to effectively have no contact with women outside of their immediate family once they leave school. Thankfully, the incest taboo is so deeply ingrained in our mammal brain that for the majoirty of them they'll get by with VR porn and vtubers. But there's going to be a portion of them that won't be satisfied with just that and will go for whatever they have available to them.
I'm hoping that I'm just autistic and looking way too deeply into this, but I'm starting to see the kind of extreme isolation that heavily contributes to incest occurring being replicated across wider society, and it legitimately has me concerned.
