Celebrated economist Jeffrey Sachs has a plan to eliminate extreme poverty around the world by 2025. If you think that is too ambitious or wildly unrealistic, you need to read this book. His focus is on the one billion poorest individuals around the world who are caught in a poverty trap of disease, physical isolation, environmental stress, political instability, and lack of access to capital, technology, medicine, and education. The goal is to help these people reach the first rung on the "ladder of economic development" so they can rise above mere subsistence level and achieve some control over their economic futures and their lives.
To do this, Sachs proposes nine specific steps, which he explains in great detail in The End of Poverty. Though his plan certainly requires the help of rich nations, the financial assistance Sachs calls for is surprisingly modest--more than is now provided, but within the bounds of what has been promised in the past.
