Karl Marx's historical materialism posits that the economic base of society, specifically the mode of production, determines the social, political, and intellectual superstructure. Central to this analysis are class relations, which arise from the ownership and control of the means of production. The struggle between the bourgeoisie and the proletariat is the primary driver of historical change, making class relations essential to understanding the dynamics of power and social structure in Marxian theory.

Syndicalism is a revolutionary movement that advocates for the organization of society through labor unions or 'syndicates.' Syndicalists believe that the state should be abolished and replaced by these worker-led organizations, which would manage the economy and social functions directly. This approach emphasizes direct action and the decentralization of power, moving away from traditional state-centric governance toward a system managed by the producers themselves.

Karl Marx is considered the most significant advocate and intellectual founder of Communism. His seminal works, including 'The Communist Manifesto' and 'Das Kapital', provided the theoretical framework for historical materialism and class struggle, which became the bedrock of communist ideology globally. While Friedrich Engels was his close collaborator, Marx is universally acknowledged as the primary figurehead of the movement.

Ralph Miliband authored 'Parliamentary Socialism' in 1961. As a prominent Marxist political theorist, Miliband utilized this work to provide a rigorous critique of the British Labour Party, arguing that its commitment to parliamentary processes hindered the pursuit of genuine socialist transformation and systemic change within the capitalist state structure.

Marxism is fundamentally revolutionary rather than reformist. It rejects the idea that peaceful, constitutional methods within a capitalist framework can achieve the necessary structural changes. Instead, it advocates for the overthrow of the existing order through class struggle, making the assertion that it relies on peaceful reform fundamentally incorrect within the context of Marxist theory.

Karl Marx posited that during the transitional phase known as the dictatorship of the proletariat, the state would seize the means of production from the bourgeoisie. The goal of this transition is to reorganize production to serve the collective interest of society rather than private profit. By eliminating class exploitation, the means of production are directed toward the 'social good,' eventually paving the way for a stateless, classless communist society.

Karl Marx famously articulated in the Rules of the International Workingmen's Association that the liberation of the working class must be achieved by the workers themselves. This principle emphasizes the necessity of self-emancipation, collective agency, and the rejection of reliance on external bourgeois forces to secure the rights and freedom of the proletariat within the capitalist system.

Pareto's distinction between 'speculators' (who rely on innovation and change) and 'rentiers' (who rely on stability and tradition) mirrors the class-based analysis found in Marxist theory. While Pareto focused on the circulation of elites, his categorization of these groups reflects the economic and power-based divisions that Marx identified in his analysis of the bourgeoisie and the ruling class, highlighting the structural tensions within society.

Socialist thought focuses on the equitable distribution of resources and the elimination of class-based exploitation. By prioritizing the material conditions of society, socialists argue that justice cannot be achieved without addressing the economic disparities inherent in capitalist structures.

This perspective is central to Marxist theory, particularly as articulated by Friedrich Engels. Marxists argue that the state is not a neutral arbiter but an instrument of class rule that arises to manage the conflicts inherent in a society divided by economic classes. According to this view, the state exists to maintain the dominance of the ruling class, and it will eventually wither away once class antagonisms are abolished.
