But the alienation from the results of their production is just one component of the alienation Marx proposed. In addition to the alienation from the results of production, the proletariat is also alienated from each other under capitalism. Capitalists alienate the proletariat from each other by forcing them to compete for limited job opportunities. Job opportunities are limited under capitalism in order for capitalists to keep wages down; without a pool of extraneous workers, capitalists would have to meet the wage demands of their workers. Because they are forced to compete with other members of the proletariat, workers are alienated from each other, compounding the unhappiness of the proletariat.

Marx and Engels emphatically wrote in The Manifesto of the Communist Party (1848), ‘Let the ruling classes tremble at a communist revolution. The proletarians have nothing to lose but their chains. They have a world to win. Workers of all countries unite.’ Marx’s proposed solution to human alienation was for the proletariat to unite and through protests or revolution (or legislation in democratic nations) overthrow the bourgeoisie and institute a new form of government – communism. This form of government would be based on communally owned and highly developed means of production and self-governance. The means of production would be developed to the point that everyone in society would have sufficient 'free' time to allow them to participate in whatever governmental decisions needed to be made for the community as a whole. By re-connecting the individual with the fruits of their labor and empowering them toward true self-governance, species being would be realized and happiness would be returned.

Two additional comments are in order here. First, the communism that developed in The Soviet Union and China - as well as other parts of the world - was not the communism envisioned by Marx. These forms of communism still had stratified hierarchies with two groups: a ruling elite and everybody else. Second, Marx believed capitalism, while harmful to species being, was necessary to advance the means of production to a stage where communism (as he envisioned it) could be realized. Thus, while Marx was highly critical of capitalism, he also recognized its utility in developing the means of production.

Durkheim and Solidarity

Durkheim's view of society and the changes it was undergoing as a result of industrialization also led him to believe unhappiness was a possible outcome. Durkheim believed that an important component of social life was social solidarity, which is understood as a sense of community. In his classic study, Suicide, Durkheim argued that one of the root causes of suicide was a decrease in social solidarity â€" termed anomie (French for chaos) by Durkheim. Durkheim also argued that the increasing emphasis on individualism found in Protestant religions â€" in contrast to Catholicism â€" contributed to an increase in anomie, which resulted in higher suicide rates among Protestants.

In another work, The Division of Labor in Society, Durkheim proposed that pre-industrial societies maintained their social solidarity through a mechanistic sense of community and through their religious affiliations. Most people were generalists in their work â€" they farmed and created their own tools and clothing. Because they were alike in their generality, they were also more likely to share a sense of community, which Durkheim saw as an important component of happiness. In addition to their similarity in occupations, many individuals belonged to the same religious groups, which also fostered a sense of solidarity.
