Through size, corporations, once merely an efficient tool employed by individuals in the conduct of private business have become an institution-an institution which has brought such concentration of economic power that so-called private corporations are sometimes able to dominate the state. The typical business corporation of the last century, owned by a small group of individuals, managed by their owners, and limited in size by their private wealth, is being supplanted by huge concerns in which the lives of tens or hundreds of thousands of employees and the property of tens of hundreds of thousands of investors are subjected, through the corporate mechanism, to the control of a few men. Ownership has been separated from control; and this separation has removed many of the checks which formerly operated to curb the misuse of wealth and power. And, as ownership of the shares is becoming continually more dispersed, the power which formerly accompanied ownership is becoming increasingly concentrated in the hands of a few... [and] coincident with the growth of these giant corporations, there has occurred a marked concentration of individual wealth; and that the resulting disparity in incomes is a major cause of the existing depression.
