Shoot, by that metric (costs the feds more than it provides), we can get rid of well more than half the states in the union. Might be the way for the Confederacy to finally be rid of the U.S.A.!
Or we could just get rid of the states that cost twice as much as they generate in federal revenue. That would only be about ten states, and we would need passports to travel to Hawaii and Florida. The new non-United States would have a pretty balanced college football conference, with Florida, South Carolina, Alabama, Louisiana, as well as Mississippi, Kentucky, West Virginia, and even North Dakota bringing the spoiler from FBS-land. Every conference needs cellar dwellers, and that's where Hawaii and New Mexico come in.
