The federal government is currently saddled with commitments for the next three decades that it will be unable to meet in real terms. This is not new. For at least a quarter century analysts have been aware of the pending surge in baby boomer retirees.
We cannot grow out of these fiscal pressures. The modest-sized post-baby-boom labor force, if history is any guide, will not be able to consistently increase output per hour by more than 3% annually. The product of a slowly growing labor force and limited productivity growth will not provide the real resources necessary to meet existing commitments. (We must avoid persistent borrowing from abroad. We cannot count on foreigners to finance our current account deficit indefinitely.)
Only politically toxic cuts or rationing of medical care, a marked rise in the eligible age for health and retirement benefits, or significant inflation, can close the deficit. I rule out large tax increases that would sap economic growth (and the tax base) and accordingly achieve little added revenues.
With huge deficits currently having no evident effect on either inflation or long-term interest rates, the budget constraints of the past are missing. It is little comfort that the dollar is still the least worst of the major fiat currencies. But the inexorable rise in the price of gold indicates a large number of investors are seeking a safe haven beyond fiat currencies.
The United States, and most of the rest of the developed world, is in need of a tectonic shift in fiscal policy. Incremental change will not be adequate.
