Here's another way to look at $80 billion a year, including per-hour costs and a comparison to total U.S. Civil War costs.
How $80 billion breaks down:
_ $6.7 billion a month
_$1.5 billion a week
_$219 million a day
_$9.1 million an hour
_ $152,000 a minute
_ $2,500 a second
That's more than the cost of the entire Civil War: It was $5.2 billion in then-dollars, $64.1 billion in 2004 dollars.
