Final answer:
Cathy's unconventional approach to her marriage underpins capitalism through the emphasis on individualism, personal gain, and competition.
Step-by-step explanation:
In capitalism, Cathy's unconventional approach to her marriage to Edgar can underpin the system by highlighting how individuals pursue their own self-interest and seek personal gain. Her actions contribute to the idea of individualism and the pursuit of wealth, which are key principles of capitalism.
For example, Cathy may prioritize her own desires and ambitions over traditional marital roles and expectations, focusing on her own financial success rather than conforming to societal norms. This individualistic mindset aligns with the capitalist belief in personal freedom and choice.
Additionally, Cathy's approach to her marriage can be seen as a reflection of the capitalist notion of competition. By defying societal conventions and pursuing her own goals, she sets herself apart and potentially gains an advantage over others in terms of social status and economic success.
