Economist Barry Ritholtz has calculated the combined cost of the massive Federal Bailouts this year, and arrived at a total $4.6 Trillion so far.
That makes the bailout more expensive than all these programs combined (in adjusted dollars):

• Marshall Plan
• Louisiana Purchase
• Race to the Moon
• S&L Crisis
• Korean War
• The New Deal
• Invasion of Iraq
• Vietnam War
• NASA (all-time budget)

Mr. Ritholtz’s calculations are available for download, and include a lot more than the $700 Billion TARP fund.
