Similarities between wage labor and slavery were noted as early as Cicero in Ancient Rome, such as in De Officiis. With the advent of the Industrial Revolution, thinkers such as Pierre-Joseph Proudhon and Karl Marx elaborated the comparison between wage labor and slavery, and engaged in critique of work while Luddites emphasized the dehumanization brought about by machines. The introduction of wage labor in 18th-century Britain was met with resistance, giving rise to the principles of syndicalism and anarchism.
