In last night's State of the Union address President Obama proposed a three-year "spending freeze" on what amounts to one-sixth of the federal budget. Our biggest entitlement programs, Social Security and Medicare, would be excluded. These changes are optical rather than substantive. Given the spending agenda that is already in place, we can expect to see large increases in the proportion of GDP that is spent by our government for years to come.
Since 2008, the ratio of federal spending-to-GDP has risen by about 14%. From 2008 to 2009 we saw the greatest annual increase in spending in the last 30 years. In the name of stimulating job growth, the share of federal spending is now 24% of the economy, up from 21% in the last year of the Bush administration.
My analysis of data from 1950 to the present shows that periods with high tax-to-GDP ratios exhibit much slower economic growth than lower tax ratio periods. The GDP growth in high tax years (defined as years during which the ratio of tax-to-GDP was above 18%, the 60-year average) was about 1.5 percentage points lower than the growth rate in low-tax years.
