AI Summary.An analysis finds a Social Security tax-increase package lowers the debt-to-GDP ratio by 14.3 percentage points, with 97% of that coming from smaller Social Security deficits rather than economic growth. A benefit-reduction package cuts the ratio by 29.2 percentage points, raising long-run GDP by 12.1% versus 0.4%.

A Penn-Wharton simulation finds that restoring Social Security solvency with tax increases alone would cut debt/GDP by ~14pp by 2060, while a fix based only on benefit cuts would cut it by ~29pp.
How do benefit cuts and tax increases differ in reducing debt-to-GDP?
Core argument: The benefit-reduction package cuts the debt/GDP ratio by 29.2 percentage points in the long run, more than twice the 14.3 percentage points under the tax-increase package.
The first figure [in the gallery] decomposes the tax-increase reform package’s improvement to the debt/GDP ratio into separate effects: how much does it cut debt versus how much does it raise GDP? Almost all of the tax-increase plan’s improvement in debt/GDP comes from lowering federal debt by raising taxes. The plan has a small negative effect on the economy in the short run and a small positive effect in the long run. But 97% of its 14.3 percentage point long-run reduction in debt/GDP comes simply from reducing Social Security’s deficits. The economy is little-changed relative to a baseline in which Congress simply borrows to pay Social Security benefits. The benefit-reduction package [second figure in the gallery] tells a different story. It reduces debt/GDP by 29.2 percentage points, more than twice as much as the tax-increase package. Part of that comes from a larger reduction in debt: 17.2 percentage points versus 13.9. But the real kicker comes from higher long-run GDP: 12.1% under the benefit-reduction package versus just 0.4% under the tax-increase package.

The benefit-reduction package cuts the debt/GDP ratio by 29.2 percentage points in the long run, more than twice the 14.3 percentage points under the tax-increase package.
Of the tax-increase plan’s 14.3 percentage point long-run reduction in debt/GDP, 97% comes from reducing Social Security’s deficits, leaving the economy little changed relative to a baseline in which Congress borrows to pay benefits.
Long-run GDP rises 12.1% under the benefit-reduction package versus 0.4% under the tax-increase package, with debt falling 17.2 percentage points versus 13.9.

The Fairest Way to Reform Social Security May Also Be the Worst Way to Grow the Economy— Fully closing Social Security's funding gap by raising the payroll tax rate would require an immediate, permanent increase from 12.4% to 17.6%, which would reduce labor supply and economic growth. Research on a prior benefit cut found affected Americans raised earnings by 61 cents per dollar of lost benefits, generating additional payroll tax revenue.
How Federal Spending is Distributed by Age— An analysis classifying $4.4tn of $7tn in federal spending by age finds retirees aged 65 and older receive $2.7tn, 38.6% of total outlays and 61.9% of age-assignable spending, versus $1.2tn for working-age adults and $449bn for those under 26. Social Security and Medicare account for 80% of age-assignable spending on older adults.
