The federal government should be shut down more often than it currently is. In fact, we should adopt the Swiss tradition of sun setting the entire federal government so that the whole thing has to be periodically reauthorized. But, by our constitutional design the HoR holds the power of the purse as an important check on the power of the Senate, the Executive, and the Judicial and any abrogation of that power without a constitutional Ammendment would be unacceptable.
