Spy

4 numbers:

16 American spy agencies
107,000 employees (spies?)
spending $500B (since 9/11/01)

and
10 (because it looks like I.O. -Information Overload)

Air Force Intelligence Army Intelligence Central Intelligence Agency Coast Guard Intelligence Defense Intelligence Agency Department of Energy Department of Homeland Security Department of State Department of the Treasury Drug Enforcement Administration Federal Bureau of Investigation Marine Corps Intelligence National Geospatial-Intelligence Agency National Reconnaissance Office National Security Agency Navy Intelligence

the numbers work out to, by my calculation, about 360k per employee per year.
