Somebody has a Law to the effect that your expenses will always increase to match (or exceed) your income. The late Sen. Everett Dirksen, he of "A billion here, a billion there, soon you're talking about real money" fame, might have had a corollary for government spending programs and available revenue.
And then there's the Toolbox Corollary. No matter how big your toolbox is, it will eventually be so jam-packed that you won't be able to close it, and you'll need to buy a bigger one.
