Corporations engaged in interstate commerce should be regulated if they are found to exercise a license working to the public injury. It should be as much the aim of those who seek for social- betterment to rid the business world of crimes of cunning as to rid the entire body politic of crimes of violence. Great corporations exist only because they are created and safeguarded by our institutions; and it is therefore our right and our duty to see that they work in harmony with these institutions.
