I'm not sure how to answer the question. It seems to me backwards - usually one asks the question "what do I want to buy" first, rather than "what do I want to spend". I personally could be happy with a wide range of tax rates, but of course I'd expect government to provide the citizens with more services if I was paying 60% than if I was paying 30%.
Off the top of my head, I'd be willing to pay higher taxes for national health insurance, infrastructure projects in general and high-speed rail in particular, and - like many posters in this thread - to pay down the debt. There are things I'd prefer to spend less money on, too. One that comes to mind is defense projects that the Pentagon doesn't even want.
I think anyone who is voting for a rate less than they currently pay should specify what spending they'd cut to arrive at the lower tax rate. It's easy to be for tax cuts if you don't have to consider the effects.
Of course I know many of you are quite eager to cut various things out of the federal budget, so naming the programs you want to cut shouldn't present any great difficulty.
To make it harder, two things: first, do the math. It won't work to give everyone a 10% tax cut in return for cutting some $20,000 research project on reproduction in African dungbeetles.
Secondly, perhaps it would be good to present a plan for dealing with the effects of the cuts. For example, if you are going to blow away social security, as Brian wants to do... well, a lot of old folks live off their social security checks now. If there is no social security coming, what happens to the poor elderly? Are we ok with having more old people starve and/or freeze to death? Are we ok with possibly the average life expectancy going down? Or is Brian's church going to take care of all the old fogeys (and if so, where is the church going to get the money to do that?). If old farts have to work longer due to no retirement, doesn't that reduce the number of jobs available to younger people? Is it better to have old people working and young people on unemployment, or is it better to have old people on social security and young people working?
I'm not saying there aren't answers to questions like these, or that people who want to cut government haven't thought about them. I'm just saying I'd be interested in hearing the answers.
