"The White House is telling federal agencies to expect lean budgets next year, with congressional aides and lobbyists saying President Bush appears ready to propose freezing or even slightly cutting overall domestic spending."
Holding spending does not solve the social security problem, or the problem of spending more on defense.
I think a few suggestions that i have collected could help tighten the belt of the US budget.
One thing we could do is make the budget on a two year cycle, this would give us twice the time inspect the budget and cut out the pork. It could possibly cause a spending increase as the ask for money to cover two years. It would also make the budget less flexible (but then again is the goverment flexible anyways).
I do not know how laws are bundled, but they seem to be able to bundle them in complex packages. We could limit the size of the bundle, which would allow time to find the pork and cut it out. (As a side note: why do we call extra spending pork, that has got to offend some one somewhere).
