The tax rate and the level of government services need to be connected to one another. While I'm a libertarian, that's an ideological position. In the real world there are services being provided and they need to be paid for. If we'd like to stop providing those services we need to make that decision first, not take the conservative approach of shutting off the funds and watching the program flounder about before it suffocates.
It's like if you have a dog you can't take care of. Shutting it in the closet until it "goes away" is not an honorable way to go about your dilemma. But that seems to be the approach conservatives are taking in regard to our fiscal situation. They've made their "no new taxes" pledge and their sticking to it no matter the consequences.
