Final answer:
The statement is true; the notion of separate spheres and the Cult of Domesticity highlighted class distinctions by promoting a middle-class lifestyle where women focused on domestic roles, which was seen as morally superior to the working class.
Step-by-step explanation:
The notion of separate spheres and the Cult of Domesticity indeed allowed the American middle class to distinguish themselves as separate from and superior to the working class. This is true. The concept of separate spheres held that men belonged in the public sphere of work and politics, while women's domain was the private sphere of domestic life. The Cult of Domesticity further underscored this division by idealizing women's roles as mothers and homemakers, fostering a clear class distinction where middle-class families could afford to have women focus entirely on home and family, thus not needing to work outside the home for economic survival. This was a mark of social status and was contrasted with the working-class reality where often both men and women had to work outside the home. These ideologies together supported a class structure and a social order that valued the middle-class lifestyle as morally superior.
