As per Wikipedia, “Wage slavery is usually used to refer to a situation where a person’s livelihood depends on wages or a salary, especially when the dependence is total and immediate.”
Moreover, the word “factory” itself was connected in its etymology to the slave trade. In the early modern era, distant commercial outposts were known as “factories,” after the “factor,” the presiding merchant. The most notorious “factories” were the castles and prisons operated by Europeans on the coast of West Africa, where the African slave trade met the transatlantic slave trade, and whence many millions of enslaved people began the Middle Passage to the Americas. In Behemoth: A History of the Factory and the Making of the Modern World, Joshua B. Freeman doesn’t dwell on the bleak fantasies of slaveholders or the connections between early-modern colonial slavery and the rise of industry.
