 Libertarian socialists believe that by valuing freedom society works 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 Pierre-Joseph Proudhon and Karl Marx elaborated the comparison between wage labor and slavery in the context of a critique of societal property not intended for active personal use.
