Marxism

Karl Marx rejected the foundational aspects of liberal theory, hoping to destroy both the state and the liberal distinction between society and the individual while fusing the two into a collective whole designed to overthrow the developing capitalist order of the 19th century.

Vladimir Lenin stated that—in contrast with Marxism —liberal science defends wage slavery. However, some proponents of liberalism, such as Thomas Paine, George Henry Evans, and Silvio Gesell, were critics of wage slavery.

Deng Xiaoping criticized that liberalization would destroy the political stability of the People's Republic of China and the Chinese Communist Party, making it difficult for development to take place, and is inherently capitalistic. He termed it bourgeois liberalization. Thus some socialists accuse the economic doctrines of liberalism, such as individual economic freedom, of giving rise to what they view as a system of exploitation that goes against the democratic principles of liberalism, while some liberals oppose the wage slavery that the economic doctrines of capitalism allow.
