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?
I would not tell anyone that I had the money, but rather assemble several closely-knit teams of truth-seeker rationalists to work together on finding ways to improve the world via the expenditure of money. They would write reports with evidence- I would higher people I felt capable of evaluating such reports, and do what they said with the money.
