I mean, everyone agrees with stress tests for banks. I mean that's clear. But banks should do that on their own. And they should worry about their own capital functioning. That's what they should do. It shouldn't be a government function.

What I'm not saying is that all government spending is bad. It's not - far, far from it, but there is no free lunch, as a former colleague of mine used to say. There is no public tooth fairy. Father Christmas does not work on the Treasury staff this year. You can never bail someone out of trouble without putting someone else into trouble.

The income effects in an economy always sum to zero.

The tax rate increases reduce economic growth; they shrink the pie; they cause more poverty, more despair, more unemployment, which are all things government is trying to alleviate with spending.

There are lots of other things that affect state growth besides state taxes. However, the reason I look at taxes is because these are policy variables that can be changed by state governments in order to get better results than they otherwise had.

Let me just try to give you sort of the intuitive one here on the stimulus funds. If you have a two-person economy - let's imagine we have two farms, and that's the whole world, just two farms. If one of those farmers gets unemployment benefits, who do you think pays for him? Am I going way over your heads today?
