It's not a difficult concept to grasp, states are great incubators for ideas and new programs. Small enough to be held accountable, yet big enough to wield enough power/money to effect the greatest change when needed. Any programs or services can also be tailored to the populace and if they fail, it minimizes the damage to the people as a whole. If my state is a cesspool like Louisiana, I can move my family to another state with a government that serves us better. Much easier to move intra-state than out of the country.
It's just a silly pipe dream, but I would love to have my taxes flipped. Most to the state, more to the city/twnshp and little to the federal government.
