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?
True, but it would not take long radically to reduce the probability. There are tests you can perform. For example, you can try to spend some of the money.
