In some odd offensive way he is correct for the small demographic he is talking about. That is the people in their early 20's, dating, newly self-sufficient, and just starting their careers or in their mid to late 50's, recently divorced, grown children, dating, well grounded in their careers.
This doesn't do justice to any of the women raising children on their own, or dual income families struggling to pay hospital bills, mortgages, clothes, and food for children. A lot of what he is saying might be cultural, I don't know, but seems pretty traditionalist, old fashioned thinking. The days where you have a mother, father, 2 kids, and house in the suburbs with white picket fence seem to be fading. It doesn't take any kind of great mind to see that two people doing same job with same level of efficiency should be paid the same no matter what gender, race, sexual orientation, or religion.
