According to the Congressional Budget Office, the federal government spent nearly $2.5 Trillion during the 2005 fiscal year.
This means that, on average, the federal government spent nearly $6.8 billion each day, or approximately $78,418 per second.
On the sidebar of this site is a counter showing how much is being spent on the Iraqi War every second.
The Census Bureau estimates that in 2004 (the latest year for which data are available) median household income in the U.S. was $44,389.
With Bush administration spending $78,418 per second, this means that the federal government spends almost twice as much money in only one second as a typical American household earns in an entire year.
