Americans know a good deal when they see it. Today a group of  leading scientists and practitioners from several fields -- agriculture,  medicine, economics, education, engineering -- is making a proposal to  the world. If  rich and poor countries will follow through on the promises  they have made over the past five years  to fight extreme poverty and disease -- and rely on the best science and technology in doing  so -- the world can save millions of lives and extricate hundreds of millions of  its poorest people from the trap of extreme poverty. The cost is a mere 50 cents out of every $100 of rich-world income in the coming decade.
