The worker in a capitalist state — and that is his deepest misfortune — is no longer a living human being, a creator, a maker.

The worker is a mere appendage to the capitalist factory. Machinery has eliminated him. Robert Burns said: “O God, that men should be so cheap, and bread should be so dear!”

The proletarian was alienated not only because he was the servant of the bourgeois but because he became a stranger to the human condition, a sort of automaton filled with economic machinery and worked by and economic switch.

This situation does not only hold for scientific practice, it also determines the condition of the worker in the modern world. What characterizes the modern worker is the gradual decrease of the role of living work, or subjective praxis, in the real process of production, whereas the role of the objective, instrumental network continually increases, first in the form of machines in a traditional big industry and later cybernetics and robotics. The law of the gradual decrease of profit margins in the capitalist era is only the expression on the economic level of the crucial phenomenon that has come to affect modern production: the invasion of technology and its expulsion of life.

The worker is the slave of capitalist society, the female worker is the slave of that slave.

It was capitalism that allowed the body itself to go from being understood as a dynamic organism to being a working or broken machine. And it was not just the fact that new machines were increasingly part of daily life, making it seem natural to use machines as metaphors for the sciences of the age. It was also that the mode of production itself favored a reduction of people to living machines, since they were seen as working or broken in relation to their productive potential.

A person without a job under the Capitalist system is counted as nothing. Every worker has the human right to a job; yet under Capitalism, workers are dismissed form employment in times of business crisis, overproduction, depression or just to save labor costs through less workers and more speed-up. And some workers cannot find jobs in the Capitalist labor market because of lack of skills, or racial or social discrimination.

Centralization of the means of production and socialization of labor at last reach a point where they become incompatible with their capitalist integument.

Now, on the contrary, when every one is to cultivate himself into man, condemning a man to machine-like labor amounts to the same thing as slavery. If a factory-worker must tire himself to death twelve hours and more, he is cut off from becoming man. Every labor is to have the intent that the man be satisfied. [...] His labor is nothing taken by itself, has no object in itself, is nothing complete in itself; he labors only into another's hands, and is used (exploited) by this other.

It is usually assumed that, in speaking, in the 1844 Manuscripts, of man’s “being reduced to the level of the animals,” and of man’s alienation from his “species-being” under the conditions of capitalist production, Marx is thinking in terms of an abstract conception of “man” as being alienated from his biological characteristics as a species. So, it is presumed, at this initial stage in the evolution of his thought, Marx believed that man is essentially a creative being whose “natural” propensities are denied by the restrictive character of capitalism. Actually, Marx holds, on the contrary, that the enormous productive power of capitalism generates possibilities for the future development of man which could not have been possible under prior forms of productive system. The organization of social relationships within which capitalist production is carried on in fact leads to the failure to realize these historically generated possibilities. The character of alienated labor does not express a tension between “man in nature” (non-alienated) and “man in society” (alienated), but between the potential generated by a specific form of society—capitalism—and the frustrated realization of that potential. What separates man from the animals is not the mere existence of biological differences between mankind and other species, but the cultural achievements of men, which are the outcome of a very long process of social development.

In reality, the laborer belongs to capital before he has sold himself to capital. His economic bondage is both brought about and concealed by the periodic sale of himself, by his change of masters, and by the oscillation in the market price of labor power. Capitalist production, therefore, under its aspect of a continuous connected process, of a process of reproduction, produces not only commodities, not only surplus value, but it also produces and reproduces the capitalist relation; on the one side the capitalist, on the other the wage-laborer.

The masses have never believed in sophisms taught by economists, uttered more to confirm exploiters in their rights than to convert exploited! Peasants and workers, crushed by misery and finding no support in the well-to-do classes, have let things go, save from time to time when they have affirmed their rights by insurrection. And if workers ever thought that the day would come when personal appropriation of capital would profit all by turning it into a stock of wealth to be shared by all, this illusion is vanishing like so many others. The worker perceives that he has been disinherited, and that disinherited he will remain, unless he has recourse to strikes or revolts to tear from his masters the smallest part of riches built up by his own efforts; that is to say, in order to get that little, he already must impose on himself the pangs of hunger and face imprisonment, if not exposure to Imperial, Royal, or Republican fusillades.
But a greater evil of the present system becomes more and more marked; namely, that in a system based on private appropriation, all that is necessary to life and to production — land, housing, food and tools — having once passed into the hands of a few, the production of necessities that would give well-being to all is continually hampered. The worker feels vaguely that our present technical power could give abundance to all, but he also perceives how the capitalistic system and the State hinder the conquest of this well-being in every way.
Far from producing more than is needed to assure material riches, we do not produce enough.

We have increased and developed our technical ability to a degree which appears almost fantastic, and yet man has not become richer thereby; on the contrary he has become poorer. Our whole industry is in a state of constant insecurity. And while billions of wealth are criminally destroyed in order to maintain prices, in every country millions of men live in the most frightful poverty or perish miserably in a world of abundance and so-called "overproduction." The machine, which was to have made work easier for men, has made it harder and has gradually changed its inventor himself into a machine who must adjust himself to every motion of the steel gears and levers. And just as they calculate the capacity of the marvellous mechanism to the tiniest fraction, they also calculate the muscle and nerve force of the living producers by definite scientific methods and will not realise that thereby they rob him of his soul and most deeply defile his humanity. We have come more and more under the dominance of mechanics and sacrificed living humanity to the dead rhythm of the machine without most of us even being conscious of the monstrosity of the procedure. Hence we frequently deal with such matters with indifference and in cold blood as if we handled dead things and not the destinies of men.

A man is a worker. If he is not that he is nothing.
