"The family as a sphere that can't be commodified, likewise, the ideology central to Victorian ideology which pedaled the notion of separate spheres where the family was a haven in a heartless world, a bulwark against the forces of the market and the state, a haven that must be preserved in order to prevent the excesses of the market and state. The latter, a position also promoted by Smith, which emerged from ideas circulating among Scottish Englightenment thinkers."
There's a fantastic bit about this in Dickens' /Great Expectations/, wherein a legal clerk literally goes home to his "castle," divided from the street by an actual moat. The book itself is a wonderful anatomy of capitalism.
