What have the wars in Iraq and Afghanistan cost so far?

In addition to the more than one million Iraqi lives that have been lost in the war, so far, what has the financial cost been?

"The cost of the wars in Iraq and Afghanistan could total $2.4 trillion through the next decade, or nearly $8,000 per man, woman and child in the country, according to a Congressional Budget Office estimate scheduled for release Wednesday. ... In the months before the March 2003 Iraq invasion, the Bush administration estimated the Iraq war would cost no more than $50 billion."

Here are a few other ways to think about it:

-- More than $120,000 for every person in the state of New York.
-- Almost two and a half times the entire financial output of the state of New York in one year (gross state product)
-- About twice the total amount received from Federal income taxes in one year
-- Four times the cost of the entire social security program for one year
-- Close to the entire amount of income received by the Federal government in one year, from all sources (taxes, duties, social security, etc)
