Savings of the poor: Boston Globe article

From the Boston Globe:
Q and A with Daryl Collins Financial secrets of the world's poorest people.

A new book, "Portfolios of the Poor: How the World's Poor Live on $2 A Day" takes a detailed look at the daily income and expenses of 285 families in South Africa, India, and Bangladesh, studying how they pay doctors when their children get sick, put food on the table when they're out of work, and pull together money for weddings, funerals, and holidays.

The Economist article in the preceding post cites this same book, a book I am eager to see.
