This book presents a detailed explanation of the essential elements that characterize capital labor relations and the resulting social conflict that leads to repression of labor. It links repression to the class struggle between capital and labor. The starting point involves an historical approach used to explore labor repression after the American Revolution. What follows is an examination of the role of government along with the growth of American capitalism to analyze capital-labor conflict. Subsequent chapters trace US history during the 19th century to discuss the question of the role assumed by the inclusion/exclusion of capital and labor in political-economic structures, which in turn lead to repression. This book explains how and why labor continues to confront repression in the 20th and 21st centuries.
