Ten dear friends, who will recognize themselves, gave some of their free time to help me with pointers, warnings and precious fillips of encouragement along the way I cannot thank them enough, although I remain solely responsible for the basic ideas in this book, and for any errors or instances of faulty reasoning.
Next, I have a deep debt of gratitude to the World Bank. I am not speaking here in its name, and put the book together on my own and on my own time. Yet my very ability to write this kind of book comes in part from my years in this great, open-minded, knowledge-laden institution. Contrary to what many people think, it's a place where ideas are constantly debated, half like in a squabbling faculty, and half as part of the "damned-if-you-do, damned-if-you-don't" choices that keep coming up among people committed to the daunting and complex job of fighting poverty. My deep thanks in particular to Bank President Jim Wolfensohn for always giving new ideas and even maverick ways the right amount of play. And a quiet thought for his predecessor Lew Preston, who once gave me a big push forward.
Finally, my greatest debt is to my wife, Jaqueline, for her support and patience, particularly for dealing with my virtual absence and real absent-mindedness during so many shot evenings, weekends, and holidays, when I was toiling on the book on top of my usual workload.
