The author unironically writes this after pointing out that research shows that affluent families the share of families with biological parents has only dropped to 85% from 95% while the share for poor families has dropped to 30% from 95%.
The idea that the social apex has decided that family instability is unimportant is disproved by the numbers the author themselves shows.
But most such narratives are based on grievances and not facts. So it’s not surprising that the author makes claims that are not only not backed by evidence but are disproved by all the evidence the author themselves includes in their article.
