I have long been in favor of a balanced budget restriction at the level of the federal government of the United States. Because the federal government has money-creating powers it can, in fact, be very damaging if it runs a series of budget deficits. With the state government in the United States, they don't have money-creating powers. The automatic discipline imposed by the fact that they are in a common monetary unit and don't have control over the money power means that the balanced budget restriction is less needed.
