I take your point that the absolute number is important. It's a large number. It's not really a number that most people can get their head around. Forty-five billion dollars is a lot of money.
I think from a government standpoint, though, we do have to think about what our capacity to service that debt and to pay for it is, and that's where measures like debt cost as a share of GDP and debt cost versus revenues are important. I think while it is up, and those shares are up and those percentages are up versus where they were five years ago, by historical standards, they remain relatively low. That doesn't mean we can take it easy on that and not worry about it or not keep an eye on it. I think that's where ongoing fiscal prudence will be important.
