This is an academic inquiry into how labor power has been dehumanized and commodified around the world through the ages for capital accumulation and industrialization, and colonial and post-colonial economic transformation. The study explores all major episodes of slaveries beginning from the ancient civilizations to the end of Transatlantic Slave Trade in the eighteenth century; the worlds of serfdoms in the context of Western Europe, Eastern Europe, and Russia; the worlds of feudalisms in the context of Latin America, Japan, China, and India; the worlds of indentured servitudes in the context of the Europeans, the Indians, and the Chinese; the worlds of guestworkers in the contexts of the United States and Western Europe; the worlds of migrant labor programs in the context of the Gulf States; and the contemporary world of neoslavery focusing on human trafficking in both developing and developed countries, and forced labor in global value chains.
