Federal funding comes from the States. It is the State's money to begin with! The Federal government takes it by violent force and then gives some of it back like a trainer giving treats to a dog.
Long ago the federal government began to exist for it's own benefit.
If you want to argue which State would be better off (economically) independently, then that is a different argument. Louisiana may not be the economic tiger of North America but if they began charging tolls on the river they would be rolling in dough. ... Of course the federal government would step it and violently attack the Cajuns because only the Federal government has the right to fleece other States!
