The Coming Generational Storm

Laurence Kotlikoff and Scott Burns argue that American fiscal policy has committed the government to obligations far larger than its projected revenue, and that conventional deficit and debt measures conceal the problem because they record only what has already been borrowed.

The analytical apparatus is generational accounting, which Kotlikoff developed. It calculates the present value of all future government receipts and all future government expenditure, including entitlement commitments, and reports the difference as the fiscal gap. This measure treats a promise to pay future Social Security and Medicare benefits as an obligation regardless of whether it appears in the debt statistics. Their calculation produced a gap in the tens of trillions of dollars, driven principally by Medicare rather than by Social Security.

They argue that the arithmetic offers only unpleasant options: substantially higher taxes, substantially lower benefits, or inflation, and that delay increases the required adjustment because fewer workers remain to bear it. Their proposals include replacing the income tax with a consumption tax, converting Social Security to personal accounts with a government contribution, and restructuring Medicare as a voucher. The book also gives individual financial advice for readers expecting these outcomes. The fiscal gap methodology is contested on the treatment of infinite horizons and on discount rate choice, and the projections have been affected by subsequent health cost moderation. The core observation, that entitlement commitments are obligations invisible in debt statistics, is correct and remains unaddressed.
