Who are the men, who, without our realizing it, give us our ideas, tell us whom to admire and whom to despise, what to believe about the ownership of public utilities .. about immigration who tell us how our houses should be designed, what furniture we should put into them, what menus we should serve at our table, what kind of shirts we must wear, what sports we should indulge in, what plays we should see, what charities we should support, what pictures we should admire, what slang we should affect, what jokes we should laugh at?
