You are welcome to look up the studies she referred to. They are a Google search away. Would it have been helpful to show a last slide with some references? Sure. Do the studies exist she is referring to? Yes.

As to the definition of family, I thought that was very clear: the traditional nuclear family. That could have been easily garnered from the context where she talks about divorce or the welfare of children.

“Cities allow individuals to survive apart from family.”
I’d say that the many growing government dependency programs do that. The more there are the worse it gets.. As if it was by some diabolical design.

No time today... getting ready for work... I will come back to this on the weekend. But for now, it is a fact that so-called "primitive" societies (first peoples; First Nations) have strong families and no civilization. I mean that literally as "civilization" means exactly human societies in and of cities. Cities allow individuals to survive apart from family.

Read "Horatio Alger" stories. Consider "LIttle Orphan Annie" or Gail Wynand. In the days of capitalism, kids lived on their own in the city. They could find work they could do, running errands, selling newspapers.

Your glittering generalities lack numbers. Many African-American families are matriarchies with a grandmother or aunt with the mother and her child or children. In fact, that describes my family. But the plural of anecdote is not data.

See my reply to Lucky above.

This is one of many issues that are in need of dispassionate study.
Usually, as in this case, the conclusion comes first then the data is collected to suit.

Families are the building blocks of civilization.
Nuff said.
Of course the Satanic Luciferian Deep state has pushed to breakup families. This is evident in the black community whose single parent home numbers have gone from low teens to close to 70% since LBJ’s “great society” remember he LBJ said “the democrats would have the niggers vote for a hundred years”.
It is slavery to have people vote for food.
These people, the kakistocracy that has brought the US to the brink of insanity only know destruction. Regardless of color 2 competent parents are able to handle the task of raising children better than one. Good grief!

The essay by Genevieve Wood was illogical and lacking in empirical evidence. First and foremost, she never defines "family." So, what are we talking about here? More on all of this later, but I want to point out that the original essay is arguable on many grounds, both rational and real, and is therefore not objective.
