Karl Marx: Whilst the cotton industry introduced child-slavery in England, it gave in the United States a stimulus to the transformation of the earlier, more or less patriarchal slavery, into a system of commercial exploitation. In fact, the veiled slavery of the wage workers in Europe needed, for its pedestal, slavery pure and simple in the new world. Tantae molis erat, to establish the "eternal laws of Nature" of the capitalist mode of production, to complete the process of separation between labourers and conditions of labour, to transform, at one pole, the social means of production and subsistence into capital, at the opposite pole, the mass of the population into wage labourers, into "free labouring poor," that artificial product of modern society. https://wordsmith.social/protestation/quotes#quote8059
