That's not an exact quote. It wasn't some future he was worried about,
he believed it had already come to pass. Here's his article reprinted:

This bit is what has been paraphrased into the above "quote":
Private capital tends to become concentrated in few hands, partly
because of competition among the capitalists, and partly because
technological development and the increasing division of labor
encourage the formation of larger units of production at the expense
of smaller ones. The result of these developments is an oligarchy of
private capital the enormous power of which cannot be effectively
checked even by a democratically organized political society. This
is true since the members of legislative bodies are selected by
political parties, largely financed or otherwise influenced by
private capitalists who, for all practical purposes, separate the
electorate from the legislature. The consequence is that the
representatives of the people do not in fact sufficiently protect
the interests of the underprivileged sections of the population.
Moreover, under existing conditions, private capitalists inevitably
control, directly or indirectly, the main sources of information
(press, radio, education). It is thus extremely difficult, and
indeed in most cases quite impossible, for the individual citizen to
come to objective conclusions and to make intelligent use of his
political rights.
Particularly note the bit starting with "Moreover".
I'm not sure I agree with all of the conclusions, but that bit sure
seems spot on.
