I think that the reason why Federal Government attempted to return domestic policy back to the states is because of efficiency.
It is more efficient to delegate powers to the states to deal with issues and conflicts within the states because state leaders can see firsthand on what these issues are and can immediately propose and act on solutions to resolve these issues.
There are 52 states in the U.S. of A and the Federal Government can only decide on laws that can be good for all. They can't individually monitor these states to see whether the laws are implemented as it should be. Thus, they need to delegate powers to the state to act in their behalf at the same time acting for the benefit of the people living in the state.
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.
