Changing family structures will never address the root problems of a diseased system. The few ‘malignant cells’ at the top of the pyramid, who consume most of the resources, starve the rest of the social body — regardless of whether or not John and Jane have two parents or only one. The resulting inequality — which, eventually, brings exhaustion of resources and, as a consequence, violence and revolt — has brought down great civilizations repeatedly.
