But, here are some citations:
% of gdp: this one is a couple of years old, but the numbers are close enough to make the point:
Federal spending as a percent of GDP does fluctuate. Currently, it is a little more than I said:United States
Total expenditure on health per capita: $7,960
Expenditure as percent of GDP: 17.4 percent (the most)
Annual growth of total health expenditure: +2.2 percent (14th least)
Life expectancy: 78.2 years (27th highest)
So, now with more precise figures, do the math again and see if I'm not right: Take out the amount spent by the federal government for health care (Medicare, Medicaid, and Veteran's), then compare that figure with health care spending over all.With nominal GDP under our belt, we now know what the government’s spending, revenue and deficit was as a percent of GDP. In FY 2012, the federal government spent 22.77% of GDP while it took in 15.76% of GDP. The deficit came to 7.01% of GDP.
If you do the math carefully, you too will understand that health care spending (public and private) outstrips all federal spending on everything else.
