Mach you give no context to your quote, so I looked it up and found it in the book that Woodrow Wilson wrote The New Freedom
A Call For the Emancipation of the Generous Energies of a People. Here it is in context:

"Since I entered politics, I have chiefly had men's views confided to me
privately. Some of the biggest men in the United States, in the field of
commerce and manufacture, are afraid of somebody, are afraid of something.
They know that there is a power somewhere so organized, so subtle, so
watchful, so interlocked, so complete, so pervasive, that they had better
not speak above their breath when they speak in condemnation of it.

They know that America is not a place of which it can be said, as it used
to be, that a man may choose his own calling and pursue it just as far as
his abilities enable him to pursue it; because to-day, if he enters
certain fields, there are organizations which will use means against him
that will prevent his building up a business which they do not want to
have built up; organizations that will see to it that the ground is cut
from under him and the markets shut against him. For if he begins to sell
to certain retail dealers, to any retail dealers, the monopoly will refuse
to sell to those dealers, and those dealers, afraid, will not buy the new
man's wares."

It appears that Woodrow Wilson is railing against the corporate monopolies that existed in the early twentieth century.
