Women's/universal adult suffrage damaged our family unit by saying that the single voice/vote for a household is insufficient and the household must have many separate voices, thus dividing a house against itself. President Lincoln knew the perils of this.
Divorce and worse, remarriage tore into the family by saying it wasn't necessarily permanent.
Abortion, same-sex marriage, gender ideology, gang culture, public schools, all sorts of things have chipped away at family unity and said that individualism and personal sovereignty is king. Well, I'm sorry but that's just not how human beings can live.
Homelessness and poverty in general are real problems for families. Because families are unwilling to tolerate living with a relative or supporting a relative who is unwilling/incapable of supporting himself, they turn that relative out into the world and force him to fend for himself. Others live off public assistance. Public assistance is a scourge of an anti-family society that doesn't have enough religious charity to support people. The rise of the welfare state is a shameful travesty, a knock-on effect from the failure of Christianity and the family.
I've said in prior threads that there's no real poverty in these United States except where you work for it, but the true poverty, the devastating poverty, is to be alone, and isolated from one's family, and to feel rejected and unwanted. The rising culture of incels is a symptom of the family's failure to nurture and value blood relationships.
It's a shame that so many people are growing up abused and/or neglected, but that's not the fault of the abusers, it's a systemic, generational fault in society.
