The relations between family members follow two patterns: the bonds of marriage serve mostly as Machiavellian means to financial ends, while the obligations of the older generation to the young take the form of sacrifice and deprivation. Delphine is trapped in a loveless marriage to Baron de Nucingen, a money-savvy banker. He is aware of her extramarital affairs, and uses them as a means to extort money from her. Anastasie, meanwhile, is married to the comte de Restaud, who cares less about the illegitimate children she has than the jewels she sells to provide for her lover – who is conning her in a scheme that Rastignac has heard was popular in Paris. This depiction of marriage as a tool of power reflects the harsh reality of the unstable social structures of the time.
