[5] Private ownership imposes constraints on planning, leading to inaccessible economic decisions that result in immoral production, unemployment and a tremendous waste of material resources during crisis of overproduction.
[7] With no need for capital accumulation and a class of owners, private property in the means of production is perceived as being an outdated form of economic organization that should be replaced by a free association of individuals based on public or common ownership of these socialized assets.
"[12] 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.
Libertarian socialists seek to replace unjustified authority with direct democracy, voluntary federation, and popular autonomy in all aspects of life,[21] 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,[22][23] Luddites emphasized the dehumanization brought about by machines, while later American anarchist Emma Goldman famously denounced wage slavery by saying: "The only difference is that you are hired slaves instead of block slaves.
[25] Many libertarian socialists argue that large-scale voluntary associations should manage industrial manufacture, while workers retain rights to the individual products of their labor.
[27] In addition to individualist anarchist Benjamin Tucker's "big four" monopolies (land, money, tariffs, and patents), Kevin Carson argues that the state has also transferred wealth to the wealthy by subsidizing organizational centralization, in the form of transportation and communication subsidies.
"[28] Carson coined the pejorative term "vulgar libertarianism", a phrase that describes the use of a free market rhetoric in defense of corporate capitalism and economic inequality.
Later, Critical theorist Jürgen Habermas noted that the universality of modern worldviews posed a threat to marginalized perspectives outside of western rationality.
While Critical Theory emphasized the social issues stemming from capitalism with the intention towards liberating humanity, it did not directly offer an alternative economic model.
Anti-globalization and alter-globalization oppose what they view as the sweeping neoliberal and pro-corporate capitalism that spread internationally in the wake of the Soviet Union's fall.
"[34] Late philosopher Mark Fisher referred to this phenomenon as capitalist realism: "the widespread sense that not only is capitalism the only viable political and economic system, but also that it is now impossible even to imagine a coherent alternative to it.
