There's a transparency revolution sweeping the world. The more you can have transparency of payments, the more you'll be able to follow the money and the more you'll be able to see that payments for mineral rights in poor countries actually go to the people who need it, and don't get put into a kleptocrat's pocket. Transparency is terribly important for us.

There are always things that you see that are pretty tough, sure. But what keeps you going is when you see people rise above toughness and rise above really hard conditions, and make something of it.

When you go to Africa and you see people who are just like you and me - this is always my starting point. These are people who are just like you and me. The same synapses, same things are firing off in their heads, same dreams for their children, same hopes and aspirations that we all have. What can one do to reduce the possibility that their chances of a happy and healthy and prosperous life are not solely determined by the accident of where they were born?

My wish and hope, every year, is that people's life chances - their chances of having a happy, prosperous, healthy life for themselves and their family and friends - should not depend on accident of birth. It shouldn't depend on where you're born. It should depend on who you are and what you do. But it shouldn't depend on the chance and the luck of being born in the U.S. or in a poor village in Sub-Saharan Africa or India or wherever it may be.
