The challenge is going to come from Russia. The challenge is not going to come from the United States. The challenge is not going to come from West Germany nor from France. The challenge is going to come from those countries who, however wrong they may be – and I think they are wrong in many fundamental respects – nevertheless are at long last being able to reap the material fruits of economic planning and of public ownership. ... Our main case is and must remain that in a modern complex society it is impossible to get rational order by leaving things to private economic adventure. Therefore I am a Socialist. I believe in public ownership.
