debt

Last month's $700 billion bailout package seems staggeringly large, but it amounts to a little more than 5% of U.S. gross domestic product. Compare that to Germany's $400 billion to $536 billion rescue package (between 12% and 16% of its GDP), or Britain's $835 billion plan (30%).
Of course it may require considerably more than $700 billion to clean out our Augean Stables. But here it helps that the ratio of government debt to GDP in the U.S. runs to about 62%. For the eurozone, it's 75%; for Japan, 180%.
