A friend of mine, Rahul Deodhar, has just put out an excellent primer on poverty. He explains beautifully the concepts that I touched on in one of my early posts "The New Thinking on Poverty." The basic idea is that people move in and out of poverty based on what Rahul calls "Snakes" (pitfalls and bad habits that pull them down) and ladders (good habits and actions that pull them out). Rahul provides clear illustrations of how people can cycle in and out of poverty and the high cost of being poor. It's a free ebook and well worth the read.
