In your projections when you talked about Mr. Saxton's question with respect to if everything stayed status quo, by 2040 we would wipe out over $600 billion in debt based on the current path we are on. That seems pretty impressive to me.
I wonder if you could reconcile the statement that therefore there's limited room to implement new policies that reduce tax revenues or increase spending without introducing structural deficits. It seems to me that if over 26 years you're able to pay off $600 billion in debt, you probably can do a few policy issues. Maybe you could reconcile that for me.
