Why might working-class women not celebrate the passage of the Nineteenth Amendment?
If working class women did not celebrate the passage of the 19th Amendment, it would have been because they felt that they might not gain as many benefits from the right to vote as middle class women would.
During the Progressive Era, the progressives were typically middle class "native" Americans. One of their major goals was to impose their values on Americans from other classes, including the working class. Many of the reforms that the Progressives tried to implement were aimed at changing the ways of the working class.
Women of the working class might have felt that the 19th Amendment would simply give more power to the middle class progressives. The middle class women would be the ones most likely to vote and, therefore, to have influence over government. This might have led to more reforms that would have been used to change the ways of the working class. It is likely that women of the working class would not have welcomed such a change.
