We also can press governments around the world to spend taxpayer money in ways that better reflect the values of the people who pay the taxes. If we can find approaches that meet the needs of the poor in ways that generate profits for business and votes for politicians, we will have found a sustainable way to reduce inequity in the world. This task is open-ended. It can never be finished. But a conscious effort to answer this challenge will change the world. I am optimistic that we can do this, but I talk to skeptics who claim there is no hope. They say: "Inequity has been with us since the beginning, and will be with us till the end - because people just … don't … care." I completely disagree. I believe we have more caring than we know what to do with. All of us here in this Yard, at one time or another, have seen human tragedies that broke our hearts, and yet we did nothing - not because we didn't care, but because we didn't know what to do. If we had known how to help, we would have acted. The barrier to change is not too little caring; it is too much complexity. To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps. Even with the advent of the Internet and 24-hour news, it is still a complex enterprise to get people to truly see the problems.
