The lead essay by Barbara and John Ehrenreich opens the debate about the nature of the "middle class." Do those who work between labor and capital constitute a third class, or will different sectors tend to ally with either the working class or the capitalist class, or is a whole new conception of the dynamics of social change necessary?

This treatment offers a model of globalization by examining international labor, finance, and capital flows.

Find a pool of cheap, pliable workers and give them jobs—and soon they cease to be as cheap or as pliable. What is an employer to do then? Why, find another poor community desperate for work. This route—one taken time and again by major American manufacturers—is vividly chronicled in this fascinating account of RCA's half century-long search for desirable sources of labor. Capital Moves introduces us to the people most affected by the migration of industry and, most importantly, recounts how they came to fight against the idea that they were simply "cheap labor." Jefferson Cowie tells the dramatic story of four communities, each irrevocably transformed by the opening of an industrial plant. From the manufacturer's first factory in Camden, New Jersey, where it employed large numbers of southern and eastern European immigrants, RCA moved to rural Indiana in 1940, hiring Americans of Scotch-Irish descent for its plant in Bloomington. Then, in the volatile 1960s, the company relocated to Memphis where African Americans made up the core of the labor pool. Finally, the company landed in northern Mexico in the 1970s—a region rapidly becoming one of the most industrialized on the continent.

In this empirical study, Saskia Sassen offers a fresh understanding of the processes of international migration. Focusing on immigration into the US from 1960 to 1985 and the part played by American economic activities abroad, as well as foreign investment in the US, she examines the various ways in which the internationalization of production contributes to the formation and direction of labor migration.

This examination of the 120-year-old American system of privatized social insurance 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.

Capital, Labor, and State is a systematic and thorough examination of American labor policy from the Civil War to the New Deal. David Brian Robertson skillfully demonstrates that although most industrializing nations began to limit employer freedom and regulate labor conditions in the 1900s, the United States continued to allow total employer discretion in decisions concerning hiring, firing, and workplace conditions. Robertson argues that the American constitution made it much more difficult for the American Federation of Labor, government, and business to cooperate for mutual gain as extensively as their counterparts abroad, so that even at the height of New Deal, American labor market policy remained a patchwork of limited protections, uneven laws, and poor enforcement, lacking basic national standards even for child labor.

Workers and Capital is universally recognised as the most important work produced by operaismo, a current of political thought emerging in the 1960s that revolutionised the institutional and extra-parliamentary Left in Italy and beyond. In the decade after its first publication in 1966, the debates over Workers and Capital produced new methods of analysis and a new vocabulary for thousands of militants, helping to inform the new forms of workplace, youth and community struggles. Concepts like 'neocapitalism', 'class composition', 'mass-worker', 'the plan of capital', 'workers' inquiry' and 'co-research' became an established part of the Italian Left's political lexicon. Over five decades since it was first published, Workers and Capital is a key text in the history of the international workers' movement, yet only now appears in English translation for the first time. Far from simply an artefact of the intense political conflicts of the 1960s, Tronti's work offers extraordinary tools for understanding the powerful shifts in the nature of work and class composition in recent decades.
