    We have no hereditary aristocracy or landed gentry, and even the poorest among us feel that they can become rich through education, hard work, or sheer gumption. And yet social class remains a powerful force in American life.In Class Matters, a team of New York Times reporters explores the ways in which class--defined as a combination of income, education, wealth, and occupation--influences destiny in a society that likes to think of itself as a land of opportunity. We meet individuals in Kentucky and Chicago who have used education to lift themselves out of poverty and others in Virginia and Washington whose lack of education holds them back. We meet an upper-middle-class family in Georgia who moves to a different town every few years, and the newly rich in Nantucket whose mega-mansions have driven out the longstanding residents. And we see how class disparities manifest themselves at the doctor's office and at the marriage altar.For anyone concerned about the future of the American dream, Class Matters is truly essential reading.Class Matters is a beautifully reported, deeply disturbing, portrait of a society bent out of shape by harsh inequalities. Read it and see how you fit into the problem or--better yet--the solution!--Barbara Ehrenreich, author of Nickel and Dimed and Bait and Switch

    

    Stimulating, illuminating, and always surprising, The Big Questions challenges readers to re-evaluate their most fundamental beliefs and reveals the relationship between the loftiest philosophical quests and our everyday lives.

    Once the party of anti-communism and tax-cutting under President Kennedy, it is now dominated by a surging socialist movement and led by a presidential candidate who vows to "transform" America.On a near-daily basis, the Democrats are issuing radical proposals to socialize medicine, industry, and higher education. So how can the Democrats win elections when their agenda is so far to the left of the American people?That's easy--it's because the means of public debate are being manipulated.In Countdown to Socialism, Congressman Devin Nunes exposes the nexus between the Democratic Party, the mainstream media, and the social media corporations. These three entities cooperate to blast out the Democrats' message and downplay their extremism while suppressing and censoring conservative points of view.Tens of millions of Americans are only seeing one side of the debate. The information they get from newspapers and social media is not "news"--it's contrived content designed to help one political party and punish its opponents.In the run-up to the most consequential election of our lifetime, read this book to learn how your information is being skewed and regulated to force America onto the path to socialism.

    None of these factors is either definitive or destiny. Otherwise, how to explain why Botswana has become one of the fastest growing countries in the world, while other African nations, such as Zimbabwe, the Congo, and Sierra Leone, are mired in poverty and violence? Daron Acemoglu and James Robinson conclusively show that it is man-made political and economic institutions that underlie economic success (or lack of it). Korea, to take just one of their fascinating examples, is a remarkably homogeneous nation, yet the people of North Korea are among the poorest on earth while their brothers and sisters in South Korea are among the richest. The south forged a society that created incentives, rewarded innovation, and allowed everyone to participate in economic opportunities. The economic success thus spurred was sustained because the government became accountable and responsive to citizens and the great mass of people. Sadly, the people of the north have endured decades of famine, political repression, and very different economic institutions—with no end in sight. The differences between the Koreas is due to the politics that created these completely different institutional trajectories. Based on fifteen years of original research Acemoglu and Robinson marshall extraordinary historical evidence from the Roman Empire, the Mayan city-states, medieval Venice, the Soviet Union, Latin America, England, Europe, the United States, and Africa to build a new theory of political economy with great relevance for the big questions of today, including:    - China has built an authoritarian growth machine. Will it continue to grow at such high speed and overwhelm the West?    - Are America’s best days behind it? Are we moving from a virtuous circle in which efforts by elites to aggrandize power are resisted to a vicious one that enriches and empowers a small minority?    - What is the most effective way to help move billions of people from the rut of poverty to prosperity? More philanthropy from the wealthy nations of the West? Or learning the hard-won lessons of Acemoglu and Robinson’s breakthrough ideas on the interplay between inclusive political and economic institutions? Why Nations Fail will change the way you look at—and understand—the world.

    But much of their work is based on assumptions that are untested generalizations at best, harmful misperceptions at worst.Abhijit Banerjee and Esther Duflo have pioneered the use of randomized control trials in development economics. Work based on these principles, supervised by the Poverty Action Lab, is being carried out in dozens of countries. Drawing on this and their 15 years of research from Chile to India, Kenya to Indonesia, they have identified wholly new aspects of the behavior of poor people, their needs, and the way that aid or financial investment can affect their lives. Their work defies certain presumptions: that microfinance is a cure-all, that schooling equals learning, that poverty at the level of 99 cents a day is just a more extreme version of the experience any of us have when our income falls uncomfortably low.This important book illuminates how the poor live, and offers all of us an opportunity to think of a world beyond poverty.Learn more at www.pooreconomics.com

    Schumacher's riveting, richly researched statement on sustainability has become more relevant and vital with each year since its initial groundbreaking publication during the 1973 energy crisis. A landmark statement against "bigger is better" industrialism, Schumacher's Small Is Beautiful paved the way for twenty-first century books on environmentalism and economics, like Jeffrey Sachs's The End of Poverty, Paul Hawken's Natural Capitalism, Mohammad Yunis's Banker to the Poor, and Bill McKibben's Deep Economy. This timely reissue offers a crucial message for the modern world struggling to balance economic growth with the human costs of globalization.

    Lester Award for the Outstanding Book in Industrial Relations and Labor Economics, Princeton UniversityAn Economist Best Economics and Business Book of the YearA Financial Times Best Economics Book of the YearInequality is one of our most urgent social problems. Curbed in the decades after World War II, it has recently returned with a vengeance. We all know the scale of the problem--talk about the 99% and the 1% is entrenched in public debate--but there has been little discussion of what we can do but despair. According to the distinguished economist Anthony Atkinson, however, we can do much more than skeptics imagine."[Atkinson] sets forth a list of concrete, innovative, and persuasive proposals meant to show that alternatives still exist, that the battle for social progress and equality must reclaim its legitimacy, here and now... Witty, elegant, profound, this book should be read."--Thomas Piketty, New York Review of Books"An uncomfortable affront to our reigning triumphalists. [Atkinson's] premise is straightforward: inequality is not unavoidable, a fact of life like the weather, but the product of conscious human behavior.--Owen Jones, The Guardian
