" Finance capital, in its maturity, is the highest stage of the
concentration of economic and political power in the hands of the
capitalist oligarchy. It is the climax of the dictatorship of the
magnates of capital. At the same time it makes the dictatorship of the
capitalist lords of one country increasingly incompatible with the
capitalist interests of other countries, and the internal domination of
capital increasingly irreconcilable with the interests of the mass of
the people, exploited by finance capital but also summoned into battle
against it. In the violent clash of these hostile interests the
dictatorship of the magnates of capital will finally be transformed into
the dictatorship of the proletariat.
