They had their part but the real cause of this problem is THE PILL.
Once the pill made it possible for an unmarried woman to have sex without the fear of becoming pregnant the Feminist were unleashed to say that “A woman needs a man like a fish needs a bicycle.”

Once it became possible for a woman to become promiscuous without consequence it became possible for a man to deny his responsibilities as a father.
The end of the patriarchal society was the end of the morality of society.
