In the end, I hope poverty fighters will not let what they read in this book stop them from investing and taking risks. In the world of venture capital, a success rate of 30 percent is considered a great track record. In the world of international development, critics hold up every misstep as proof that aid is like throwing money down a rat hole. When you’re trying to do something as hard as fighting poverty and disease, you will never achieve anything meaningful if you’re afraid to make mistakes.
I greatly admire Sachs for putting his ideas and reputation on the line. After all, he could have a good life doing nothing more than teaching two classes a semester and pumping out armchair advice in academic journals. But that’s not his style. He rolls up his sleeves. He puts his theories into action. He drives himself as hard as anyone I know.
