The modern industrial wage-earner becomes a characteristic representative of that artificial race of men now growing up in cities. The labor of the modern industrial wage-worker has lost all concreteness, all qualitative significance, and so has for him only an abstract and hence purely quantitative significance. The proletariat is adopting the critical spirit, and applying it to the whole intricate field of economic and social institutions. The love of the masses and regard for the masses follows immediately from the association of each individual wage-earner with his thousands of fellow workers, all of whom are united by no other tie than their common labor in the service of the entrepreneur. The aggregated advantages of the public institutions, the public gardens and parks, and museums, with their uninterrupted series of pleasures and delights, rise in the estimation of the laborers as the charm of their private or family life diminishes.
