This paper takes issue with these optimistic views, although it recognizes that the U.S. economy may well enjoy another good year or two.

No parody is intended. No other story would make sense of the assumption now commonly made that the balance between tax receipts and public spending has no permanent effect on the evolution of the aggregate demand. And nothing else would make sense of the debate now in full swing about how to "spend" the federal surplus as though this were a nest egg that can be preserved, spent, or squandered without any need to consider the macroeconomic consequences.

The central contention of this paper is that, given unchanged fiscal policy and accepting the consensus forecast for growth in the rest of the world, continued expansion of the U.S. economy requires that private expenditure continues to rise relative to income. Yet while anything can happen over the next year or so, it seems impossible that this source of growth can be forthcoming on a strategic time horizon. The growth in net lending to the private sector and the growth in the growth rate of the real money supply cannot continue for an extended period. Moreover, if, per impossibile, the growth in net lending and the growth in money supply growth were to continue for another eight years, the implied indebtedness of the private sector would then be so extremely large that a sensational day of reckoning could then be at hand. In sum, if a truly strategic view is taken, covering the next 10 to 15 years, one is forced to the conclusion that the present stance of policy is fundamentally out of kilter and will eventually have to be changed radically.
