Which of the following principles did members of the grangers populists and labor unions all share

The Grange movement among farmers was similar to the labor unions because they both opposed and sought an end to coercive practices by the owners of capital. Farmers fought against monopoly in the form of railroad pricing. Labor unions fought against the owners of mills and factories. Cooperation, ownership of mills and factories, and political action through the election of representatives to state and federal office who were sympathetic to their platforms informed the Grange. The principles of cooperation, ownership of the means and modes of production, and political action informed both movements.
