The eighteenth century brought the beginning of the British cultural revolution. With the increasing power of the middle class and an expansion in consumerism, women's roles began to evolve. The economic changes brought by the new middle class provided women with the opportunity to be more directly involved in commerce. Lower-to middle-class women often assisted their husbands in work outside the home. It was still thought unseemly for a lady to be knowledgeable of business so, though some class distinctions were blurring, the upper class was able to distinguish themselves from the rest of society. The rise in consumerism allowed the gentry to place a greater emphasis on changing fashion and "display," further distancing them from the middleclass. With the advent of changes in rules of fashion and acceptable mores within society, some women established a literary niche writing etiquette guides. Also due to the cultural revolution, mounting literacy rates among the lower classes caused an increase in publishing, including the rise of the periodical. Men and women of all classes found new means to express ideas in the wider publishing community. Though women's writing during this period continued largely to be an extension of domesticity, and focused mainly on pragmatic, practical issues, women found a wider market for publication. The act of professional writing, however, was still considered "vulgar" among the aristocracy. Significant colonial expansion during this period provided would-be writers with unique subject matter—letters written by women abroad discussed foreign issues and culture, and offered a detailed view of far-off lands. These letters were often circulated among members of an extended family, as well as in the larger community. In defiance of social strictures, women such as Mary Wollstonecraft began to speak out publicly on women's rights, including education and marriage laws. Though women had better access to education, the goal of women's education was to attain an ideal "womanhood"—a "proper education" was viewed as one that supported domestic and social activities but disregarded more academic pursuits. Women such as Wollstonecraft advocated access to education for women that was equal to that of their male counterparts. Marriage laws, which overwhelmingly favored men, also spurred public debate, though little was accomplished to reform laws during this period.
