Let me be a bit more specific there. In the revenue estimates that come in every year, as you say, there's a fair amount provided in tax credits, so there are, in effect, expenditures in a sense, and there is less revenue in another sense. I think there is room for evaluating tax credits and other exemptions to the tax code to see whether they're providing the benefit they should be providing, in the same way that departments are expected to take programs and try to justify why they exist and why they are providing the benefits they do.
