Those who catch faint glimpses, in Birmingham or Notting Hill, of what others have dreaded for years, those who find themselves strangers and aliens in one familiar area after another of an English town or city, those who hear from others' lips with diminishing incredulity the circumstances in which less fortunate fellow-citizens live, should repeat to themselves over and over again one single sentence, sad, simple and true: "You have seen nothing yet". Then let them give to those who presume to represent and govern them no peace and no respite until they have led the nation from under the shadow of the disaster which overhangs it.
