The "Cult of Domesticity" was a prevailing idea (chiefly among the upper and middle classes) that a woman's "true" nature was to be domestic and therefore, be the chief caretaker of the home and that which came with it. To that end, it was made more likely with the advent of the Market Revolution and the saturation of ideas and inventions to enable a woman to "better" keep her home and family. Given the class-based nature, it is a logical conclusion because of the inherent wealth of those strata of society.
