John Stuart Mill was a proponent of what progressive policies?

John Stuart Mill was a strong advocate for women's rights and played a significant role in promoting women’s suffrage during the 19th century. His writings, particularly in "The Subjection of Women,” argue for the equality of the sexes and highlight the importance of granting women the same rights and opportunities as men, including the right to vote. Mill believed that society could not progress fully without the participation of women in civic life.

Additionally, he supported the rights of workers and the establishment of labor unions, which aimed to improve working conditions and promote fair wages. Mill recognized the importance of organizing workers to collectively negotiate with employers, and he championed ideas of social reform that would benefit the working class.

His advocacy for these progressive policies reflects a broader concern for individual rights, social justice, and the need for reforms to create a more equitable society, making the choice focused on women’s suffrage and labor unions the most aligned with Mill's principles.
