Timber... let us say the twist manages to force interest rates on average down to 2%.
Let us say there is a recovery, and the interst rates rise to a whooping 3%. A 50% increase.
Is your postion then, that a recovery will increase tax revenues 50% to (porportionally) cover the increase in interest payable.
