And what is their principle, whose protector they always 'love'? Not that of labour", rather it is "interest-bearing possession ... labouring capital, therefore ... labour certainly, yet little or none at all of one's own, but labour of capital and of the—subject labourers"." French anarchist Pierre Joseph Proudhon opposed government privilege that protects capitalist, banking and land interests, and the accumulation or acquisition of property (and any form of coercion that led to it) which he believed hampers competition and keeps wealth in the hands of the few. The Spanish individualist anarchist Miguel Gimenez Igualada saw "capitalism [as] an effect of government; the disappearance of government means capitalism falls from its pedestal vertiginously...That which we call capitalism is not something else but a product of the State, within which the only thing that is being pushed forward is profit, good or badly acquired. And so to fight against capitalism is a pointless task, since be it State capitalism or Enterprise capitalism, as long as Government exists, exploiting capital will exist. The fight, but of consciousness, is against the State.". Within anarchism there emerged a critique of wage slavery which refers to a situation perceived as quasi-voluntary slavery, where a person's livelihood depends on wages, especially when the dependence is total and immediate. It is a negatively connoted term used to draw an analogy between slavery and wage labor by focusing on similarities between owning and renting a person. The term "wage slavery" has been used to criticize economic exploitation and social stratification, with the former seen primarily as unequal bargaining power between labor and capital (particularly when workers are paid comparatively low wages, e.g. in sweatshops), and the latter as a lack of workers' self-management, fulfilling job choices and leisure in an economy. Libertarian socialists believe if freedom is valued, then society must work towards a system in which individuals have the power to decide economic issues along with political issues. Libertarian socialists seek to replace unjustified authority with direct democracy, voluntary federation, and popular autonomy in all aspects of life, including physical communities and economic enterprises. With the advent of the industrial revolution, thinkers such as Proudhon and Marx elaborated the comparison between wage labor and slavery in the context of a critique of societal property not intended for active personal use, Luddites emphasized the dehumanization brought about by machines while later Emma Goldman famously denounced wage slavery by saying: "The only difference is that you are hired slaves instead of block slaves.". American anarchist Emma Goldman believed that the economic system of capitalism was incompatible with human liberty.
