Which of the following was NOT a demand of the Populist Party?

The demand for an increase in tariffs was not a position supported by the Populist Party, which primarily represented the interests of farmers and laborers in the late 19th century. The Populist Party advocated for reforms that would benefit the common person, particularly promoting measures that would lower costs for agricultural workers and the working class. High tariffs were generally seen as benefiting industrialists at the expense of farmers by raising the cost of imported goods. Conversely, the Populist Party did push for other reforms such as shorter workdays, a national income tax to ensure that wealthier individuals contributed more to government revenue, and government control of railroads to reduce shipping costs and improve access. These demands aligned with the party's goal to address the economic inequality faced by their constituents.
