Timothy Noah, in his new book, The Great Divergence, discusses how America has steadily become a nation of haves and have-nots in the past three decades. Our incomes are increasingly drastically unequal: The top 1 percent of Americans collect almost 20 percent of the nation’s income—more than double their share in 1973. We have less equality of income than Venezuela, Kenya, or Yemen. The income gap has been blamed on everything from computers to immigration, but its causes and consequences call for a patient, nonpartisan exploration. In The Great Divergence, Timothy Noah delivers this urgently needed inquiry, ignoring political rhetoric and drawing on the best work of contemporary researchers to peer beyond conventional wisdom. Noah explains not only how the Great Divergence has come about, but why it threatens American democracy—and most important, how we can begin to reverse it.
