The corporation as a form severs the direct link between capital and its individual owner, and monopoly capitalism builds upon this form.  Huge aggregates of capital may be assembled that far transcend the sum of the wealth of those immediately associated with the enterprise.  And operating control is vested increasingly in a specialized management staff for each enterprise.  Since both capital and professional management--at its top levels--are drawn, by and large, from the same class, it may be said that the two sides of the capitalist, owner and manager, formerly united in one person, now become aspects of the class (179).
