Out-of-context quote of the day:
"...although even $10 trillion isn't a huge amount of money..."
From Simon Johnson, Director of the IMF's Research Department, on "The Rise of Sovereign Wealth Funds".
So if you had $10 trillion, what would you do with it?
Whereas for the US federal government, the question is "So if you owed $10 trillion, what would you do about it?"
That's about 15% of gross world product, by the way.
