It is enough to mention the commercial crises that, by their periodical return, put the existence of the entire bourgeois society on its trial, each time more threateningly. In these crises, a great part not only of the existing products, but also of the previously created productive forces, are periodically destroyed. Because there is too much civilization, too much means of subsistence, too much industry, too much commerce. The conditions of bourgeois society are too narrow to comprise the wealth created by them. That is to say, by paving the way for more extensive and more destructive crises, and by diminishing the means whereby crises are prevented.
Wage labor rests exclusively on competition between the laborers.
The advance of industry, whose involuntary promoter is the bourgeoisie, replaces the isolation of the laborers, due to competition, by the revolutionary combination, due to association. The development of Modern Industry, therefore, cuts from under its feet the very foundation on which the bourgeoisie produces and appropriates products. What the bourgeoisie therefore produces, above all, are its own grave-diggers. Class struggle underlies most political struggle. Race and gender related oppression and struggle are some of the foremost examples of struggle that is not based on class.
