During the Progressive Era, one of the goals of politicians was to ensure safe working conditions. This period, which roughly spanned from the 1890s to the 1920s, focused on addressing social issues caused by industrialization, including labor rights and workplace safety.
While the direct election of senators (the Seventeenth Amendment) did occur during this time, ensuring safe working conditions was more aligned with the broader Progressive movement's objectives. The provision of "more common drinking cups" is not typically associated with the major goals of the era.
