In proportion as the bourgeoisie, i.e., capital, is developed, in the same proportion is the proletariat, the modern working class, developed - a class of labourers, who live only so long as they find work, and who find work only so long as their labour increases capital. These labourers, who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.
Karl MarxBy the aristocracy of finance must here be understood not merely the great loan promoters and speculators in public funds, in regard to whom it is immediately obvious that their interests coincide with the interests of the state power. All modern finance, the whole of the banking business, is interwoven in the closest fashion with public credit.
