Quote #4
This organisation of the proletarians into a class, and consequently into a political party, is continually being upset again by the competition between the workers themselves. But it ever rises up again, stronger, firmer, mightier. (Section1.40)
Marx seems to be arguing that what's actually in the best interest of the workers is to come together in full cooperation against the bourgeoisie. Yet this does not occur, because the market requires workers to compete against each other. So to what extent does competition harm us by keeping us from cooperating?
Quote #5
The bourgeoisie finds itself involved in a constant battle. At first with the aristocracy; later on, with those portions of the bourgeoisie itself, whose interests have become antagonistic to the progress of industry; at all times, with the bourgeoisie of foreign countries. In all these battles it sees itself compelled to appeal to the proletariat, to ask for its help, and thus, to drag it into the political arena. The bourgeoisie itself, therefore, supplies the proletariat with its own elements of political and general education, in other words, it furnishes the proletariat with weapons for fighting the bourgeoisie. (Section1.41)
It might seem like the bourgeoisie would only be interested in subjecting the proletariat. But because the capitalists are constantly in competition with each other, they also have to use their own workers to advance their individual interests during these battles. That means training for the workers. Is Marx right that the ways workers are trained by the bourgeoisie also gives them the tools to fight back? Consider the contrasting view of civil rights activist Audre Lorde. She wrote, in her words, that the master's tools can never be used to dismantle the master's house.
Quote #6
Further, as we have already seen, entire sections of the ruling classes are, by the advance of industry, precipitated into the proletariat, or are at least threatened in their conditions of existence. These also supply the proletariat with fresh elements of enlightenment and progress. (Section1.42)
Even if a person is born rich, there is always the possibility of losing that money. Imagine that happening to someone. How might it help the poor or the workforce? How might it not?
