I came across Dr. Warren Farrell's work a few years ago, when I read Why Men Earn More, a careful study of the many reasons for the existence of the ""gender pay gap,"" attributed by ideologues of the identity-politics persuasion to systemic patriarchal prejudice and oppression. Farrell has recently published another book, "The Boy Crisis" with Dr. John Gray. We spent an intense 90 minutes discussing the crucial role played by fathers in child development.
