@Andrew Gubb - One of the most notable "tax cuts" he's going to make is to abolish the IRS, therefore stopping us from being charged income tax. Income tax consumes 2-3 months worth of YOUR money, from YOUR labor. This alone will stimulate massive economic change, and he plans to do much more than this.
I think I'm on your side in this, Ron Paul inspires me -- but I don't think your answer quite works. I asked what is being cut - I mean what expenses are being cut - so that taxes can be lowered. But the IRS isn't an expense right? Not to the government. The IRS brings in money to the government, but if we cut expenses, it won't be needed and can be cut itself.
