Leon Trotsky was a prominent proponent of the theory of 'Permanent Revolution.' He argued that in underdeveloped nations, the bourgeois-democratic revolution would inevitably transition into a socialist revolution, and that the survival of this revolution depended on its expansion internationally to prevent isolation and counter-revolutionary pressures from capitalist powers.

Karl Marx argued that the state is not a neutral entity but an instrument used by the ruling class to maintain dominance over the proletariat. In his view, the state apparatus serves to protect the interests of those who own the means of production, thereby facilitating the exploitation of the working class within a capitalist framework.

Socialist thought posits that true justice cannot exist without economic and social equality. Socialists argue that systemic inequalities, particularly those arising from private ownership of the means of production, prevent individuals from achieving their full potential. Therefore, achieving justice requires the redistribution of wealth and resources to ensure a more equitable society, where the benefits of collective labor are shared among all members, rather than concentrated in the hands of a few.

The Soviet Union operated under a command economy, which is the antithesis of a capitalist system. In the Soviet model, the state held ownership of the means of production, land, and resources, and central planning authorities determined production quotas and prices. Private property and market-driven competition, which are the hallmarks of capitalism, were largely absent from the Soviet economic framework.

Critics of Marx often point out that his focus on the proletariat and the eventual 'dictatorship of the proletariat' leaves little room for the protection or integration of non-working classes or those who do not fit into his binary class struggle model. This critique suggests that his framework lacks sufficient safeguards for individual rights and pluralism, potentially leading to the marginalization of groups outside the revolutionary working class.

This statement appears in the General Rules of the International Workingmen's Association, drafted by Karl Marx in 1864. It encapsulates the core Marxist principle of self-emancipation, arguing that the proletariat must organize and act independently to overthrow capitalist structures rather than relying on external saviors or bourgeois reforms.

Critics of Marxism argue that the binary model of the bourgeoisie and proletariat is overly simplistic, failing to account for the complexity of modern social stratification. Furthermore, historical developments in capitalist economies have shown a significant expansion of the middle class, contradicting the Marxian prediction of inevitable polarization and the eventual collapse of capitalism.

Karl Marx, along with Friedrich Engels, provided the foundational theoretical framework for communism. His works, such as 'The Communist Manifesto' and 'Das Kapital', analyzed historical development through the lens of class struggle and material conditions, advocating for the eventual overthrow of capitalism and the establishment of a classless, stateless society.

Schumpeter acknowledged that his view of economic development as a process of discontinuous, 'disharmonious' leaps was heavily influenced by Karl Marx. Marx viewed the development of capitalism as a series of crises and revolutionary changes in the forces of production, a perspective Schumpeter adapted to explain the cyclical nature of innovation and growth in capitalist economies.

The term 'largest garage sale in history' is a common metaphor used to describe the rapid and often chaotic privatization of state-owned assets in the former Soviet Union during the 1990s. This 'Shock Therapy' involved the sudden transition from a command economy to a market economy, resulting in the sale of vast state industries to private individuals, which led to significant economic upheaval and the rise of oligarchs.
