Like most people, I too feel that we need better infrastructure and health care and education. But I also believe that each of us must try, in our individual capacity, what we can to solve the problem. Each one can teach one to fish, so he does not have to beg for lunch the next day. Our effort in this direction is currently taking the route of a global competition, in London in October 2012. You can read about it here http://www.3d4dchallenge.org/finalists/just-3d-printing/. We hope we can do it and make a difference. Thanks.
