Why are pension funds so large and benefits so small? This examination of the 120-year-old American system of privatized social insurance - often called, at 1.7 trillion dollars, the biggest lump of money in the world - reveals that the system fails to provide adequate retirement income security, its most prominent goal, and, in fact, its greatest influence is in supplying funds to U.S. capital markets.Linking market forces, historical movements, and social norms in the evolution of pensions, Ghilarducci's study is the first to focus on all major aspects of the system. Its trenchant analysis of the many sides of pensions and pension policy addresses questions of whom the system benefits, its direct and social costs, and the possibilities of reforms that would take into account the related problems of capital formation and retirement income.Ghilarducci describes the history of pension funds and the involvement of unions in bargaining. She takes up the "moral hazard" involved in the conflicting interests of corporations and their employees, tackling issues of information availability and inequality of pension distribution based on sex, race, and job hierarchy. And in two chapters, each focusing on corporate and union uses of pension funds, she covers such topics as tax breaks, the effect of corporate takeovers, the use of pensions to pay back debt, and the kinds of skimming that can occur despite government regulation of pension activities. Ghilarducci concludes by presenting an ideal pension plan that would benefit both employer and employee and by offering predictions about pension plans of the future.
