Any level of government would then support the next higher level of government in the hierarchy of government. Currently, the hierarchy is the federal government, the state governments, and the county and local governments. County and local governments have an equivalent level of jurisdiction, both being chartered by the state.
Every level taxes individual people.
A better hierarchy would be the federal government, the state governments, the county governments, and then the local governments, with local governments being chartered by the county governments. For the purposes of taxation, the federal government would have the power to tax anything within its jurisdiction that is not within the jurisdiction of a more local level of government. The state government would have the power to tax anything within its jurisdiction that is not within the jurisdiction of a more local level of government. The county government would have the power to tax anything within its jurisdiction that is not within the jurisdiction of a more local level of government. The local government would have the power to tax anything within its jurisdiction.
