>In the capitalist mode of production, the generation of products (goods and services) is accomplished with an endless sequence of discrete, repetitive motions that offer the worker little psychological satisfaction for "a job well done." By means of commodification, the labour power of the worker is reduced to wages (an exchange value); the psychological estrangement (Entfremdung) of the worker results from the unmediated relation between his productive labour and the wages paid to him for the labour.
Less often discussed is Marx's view of social alienation in this context: i.e., workers used to take pride in who they are based on their occupation. 'I am the best blacksmith in town.' Automation destroyed that for workers, and it'll come for you/us, too.
