The fundamental units of analysis in constitutional economics are the decisions of individuals, and not the federal government. It is the individual's money, not the government. Legislatures seem to act in the "public interest" when they spend money other than their own without the people's consent. However, sound management dictates public choice and competition from the very private sector that provides the revenue to the government. Each and every public good or service, whether it be health services, education, transportation, or defense tends to be expanded well beyond any tolerable level of efficiency as defined by the demands of the citizenry.
