The result, then, is that the Negroes thus mis-educated are of no service to themselves and none to the white man. The white man does not need the Negroes' professional, commercial or industrial assistance; and as a result of the multiplication of mechanical appliances he no longer needs them in drudgery or menial service. The "highly educated" Negroes, moreover, do not need the Negro professional or commercial classes because Negroes have been taught that whites can serve them more efficiently in these spheres.
