"...the concentration of capital and the growth of their turnover
is radically challenging the significance of the banks. Scattered
capitalists are transformed into a single collective capitalist. When
carrying the current accounts of a few capitalists, the banks, as it
were, transact a purely technical and exclusively auxiliary operation.
When, however, these operations grow to enormous dimensions
we find that a handful of monopolists control all the operations,
both commercial and industrial, of capitalist society.
They can, by means of their banking connections."
