Well, I must admit that is true, but I guess that 20% of the annual budget going toward interest feels likean impossibly large fraction to overcome. But yes, theoretically, if GDP grew by 300% in the next year, the debt would shrink proportionately, and I would feel much better about not needing to make any cuts. I suppose my concern is that with the nature of the business cycle, we will run into a recession sooner or later, and when that happens, if GDP and tax revenues both go down for a sustained period, then I would worry that lenders would become hesitant to provide additional funding. But I suppose that would be a complicated situation with many other factors, so maybe I am worrying too much.
This is logically (and in a simple way) false. Incomes could also increase.
