That is always a possibility isn't it? This is why there should be no rush to such a decision. However centralization of power in a growing federal government is not the answer. I would suggest that a smaller central government with limited delegated powers such as those outlined in the Constitution leaving significant powers of government to the states and local communities would allow local communities a sense of self-empowerment necessary to create a sense of loyalty to the union. Otherwise communities differing from the central government will yearn for the freedom to follow their own path.
