Senator Everett Dirksen (R, Ill.) was one of the more colorful members in the history of the United States Senate. A fiscal conservative, he is commonly remembered for having said:"A billion here, a billion there; soon you're talking about real money." Dirksen could not have imagined the magnitude of the bailout to which the United States is already committed. Barry Ritholz,"Big Bailouts, Bigger Bucks," The Big Picture, 25 November, puts it this way:

If we add in the Citi bailout, the total cost now exceeds $4.6165 trillion dollars. People have a hard time conceptualizing very large numbers, so let's give this some context. The current Credit Crisis bailout is now the largest outlay In American history.
Jim Bianco of Bianco Research crunched the inflation adjusted numbers. The bailout has cost more than all of these big budget government expenditures – combined:

• Marshall Plan: Cost: $12.7 billion, Inflation Adjusted Cost: $115.3 billion
• Louisiana Purchase: Cost: $15 million, Inflation Adjusted Cost: $217 billion
• Race to the Moon: Cost: $36.4 billion, Inflation Adjusted Cost: $237 billion
• S&L Crisis: Cost: $153 billion, Inflation Adjusted Cost: $256 billion
• Korean War: Cost: $54 billion, Inflation Adjusted Cost: $454 billion
• The New Deal: Cost: $32 billion (Est), Inflation Adjusted Cost: $500 billion (Est)
• Invasion of Iraq: Cost: $551b, Inflation Adjusted Cost: $597 billion
• Vietnam War: Cost: $111 billion, Inflation Adjusted Cost: $698 billion
• NASA: Cost: $416.7 billion, Inflation Adjusted Cost: $851.2 billion
TOTAL: $3.92 trillion

That is $686 billion less than the cost of the credit crisis thus far.

The only single American event in history that even comes close to matching the cost of the credit crisis is World War II: Original Cost: $288 billion, Inflation Adjusted Cost: $3.6 trillion.

The $4.6165 trillion dollars committed so far is about a trillion dollars ($979 billion dollars) greater than the entire cost of World War II borne by the United States: $3.6 trillion, adjusted for inflation (original cost was $288 billion).

A trillion here, a trillion there; ....
