In Ayn Ran's fictional books she spends an enormous amount of time describing dysfunctional society and giving illustrations of dysfunctional families. The Rearden family comes to mind from Atlas Shrugged as an example of a dysfunctional family.
Since humans are a social creatures to only present how the ideal individuals should live and act, is to fail to adequately present a philosophy that can serve and guide us. We need to know how to build families and societies.
I define a family as a social unit at minimum that consists of two people who care for one or more children.
I define society as a social unit made up of multiple families.
Does Rand's literature and philosophic works speak to and describe functional family units and how a functional society should be built?
I've read at least each of her novels 2 or 3 times: Anthem, The Fountainhead, Atlas Shrugged and about half way through Objectivism: The Philosophy of Ayn Rand by Peikoff.
