There is little popular or legislative support for giving the executive branch of government broad discretion over spending and taxes. (British, Canadian, and some other parliamentary systems permit far prompter action than is ordinarily possible in the United states.) Congress prizes its fiscal powers too highly to favor any broad relinquishment. But there is precedent for giving limited fiscal discretion to the executive branch. The Treasury has long had almost untrammeled authority to borrow up to some over-all limit, and to exercise its judgment freely as to the formas and provisions of debt issues. Billion-dollar military expenditure authorization are voted with the understanding that a substantial part may carry over to later years as part of a longer-range program. The President has discretionary power to raise or lower many tariff rates within a wide margin.
