Do you consider this dynamic relationship a good thing?

Question: In the discussion notes, it was demonstrated that there exists a dynamic power sharing relationship between the national government and the states. Power has shifted from a state-centered relationship, to a federal-centered, back towards a state-centered power sharing relationship. Do you consider this dynamic relationship a good thing? Or would it be better to have a static relationship where the power sharing was specifically defined and didn`t change? Tell us what you think and why.
