It's a nice, sweet and romantic notion. The Warren and June Cleaver type marriage was a creation of an imaginative TV scriptwriter.
All marriages have fighting and irreconcilable differences.
That's not a product of the social system, that's just life, always has been-always will be. It gives them comfort and a warm fuzzy feeling that family life really was better so they can forget about all those evil social changes that came about in the '60s. Or that strangely distant and very sad girl in their kid's class who became numb with fear whenever her father, or sometimes any male came near her. She doesn't have dreams of a career or her own plans for the future, but Dad and Jimmy-Boy do and Mom has to make sure their every need is met at her expense. Well the father I hear is the Jones boy down the road.
