(The book consists of nine chapters, from nutrition, health, education, childbirth, risk management, loans, savings, entrepreneurship and political participation. These chapters fully reveal the difficulties in the choice of the poor and the difficulties in the theory and policy of poverty eradication. This book completely distinguishes at least two states of choice. One is the choice of the poor or the non choice of the poor; The other is the choice of non poor people. It can be seen from the book that the choice needs space, and this space must be at least greater than their own clothing and food conditions, otherwise the remaining choices will be meaningless due to the scarcity of choices, or the difference between different choices is almost insignificant The Nobel Prize in economics made the book the essence of poverty a fire. To tell the truth, this is a plain book, and 90% of people don't have the patience to read it from beginning to end. Through the study of 18 poor g countries / regions, the author proves the case of a large number of poor people.)
