In fact, the lack of success in other places with such a system might even suggest that Liberal Democracy needs the same murderous impulse of the Victorians along with the need for non-conformist revolutionaries to rescue it along the way. Hitler and Stalin were new. If you read the Encyclicals you will find that the even the Catholic Church has struggled mightily with the issue of cultural cannibalism when dealing with the implications of Evangelism. It is not logical to say that what is efficient in one situation is impossible for another parallel situation. There may be such differing factors that the situations are not parallel but you haven't nor have any of the people I've read thus far, done the study on whether the processes can be separated from the cost of the Cold War to each side.

With Francis Stoner Saunder' Freedom of Information suits we now know that while Americans claimed that Socialism could never create great art, they were busy themselves funding art in Europe with American government funds including the great festival at Darmstadt, the Berlin Philharmonic and the multitudinous opera companies of Germany. The only non-State art in Germany is the Stella corporation's Broadway theaters and they are struggling with the same productivity issues that we have here. Such a shock for such arrogant souls who were convinced that we were doing something wrong here.
