Friedman reviews Acemoglu and Robinson's new book, "Why Nations Fail." Acemoglu says that nations fail when wealth and opportunities are concentrated in the hands of few people, that a condition for societies to succeed is to create opportunities for more people. For this to happen it is important to create inclusive political and economic institutions. This is an important insight, but for Western society this is an insight as old as Adam Smith when he pointed out the importance of this aspect of western societies after the feudal period in his "Wealth of Nations." For Smith it was the failure to create inclusive societies that led to the gradual unravelling of societies in the river valleys of the Yangste and the Ganges, in China and India, of increasing poverty and the gradual disappearance of what constituted the middle class in India and China. Chapter 8 titled "Of Wages and Labor" in the "Wealth of Nations" makes specific reference to this.
