Before the twentieth century,ideology- as opposed to religion - did not kill people by the millions and tens of millions. The stakes were not thought to be worth it. Such enthusiasm for mass murder awaited the combination of aristocratic militarism, really-existing socialism, and fascism. Thus it was only in the twentieth century that utopian aspirations about how the economy should be organized led nations and global movements to build dystopias to try to bring the utopian future closer. And then they turned around and justified the dystopia: compromises must be made, and this is as good as it is going to get.My view is that too much mental and historical energy has been spent parsing differences between movements that are justly classified as dystopian, and even totalitarian, in aspiration. Time spent on such a task is time wasted, given their commonalities - if not in formal doctrine, then at least in modes of operation. The guards of Auschwitz, Majdanek, Treblinka, Dachau, and the rest were very like the guards of the Gulag Archipelago.Rather, mental and historical energy should be focused on where these movements got their energy. Why was the world unable to offer people a society in which they could live good lives? Why was a total reconfiguration necessary? Karl Polanyi saw fascism and socialism as reactions against the market society's inability or unwillingness to satisfy people's Polanyian rights. It could not guarantee them a comfortable community in which to live because the use to which land was put had to pass a profitability test. It could not offer them an income commensurate with what they deserved because the wage paid to their occupation had to pass a profitability test. And it could not offer them stable employment because the financing to support whatever value chain they were embedded in also had to pass a profitability test. These failures all gave energy to the thought that there needed to be a fundamental reconfiguration of economy and society that would respect people's Polanyian rights. And the hope of millions was that fascism and really-existing socialism would do so.Instead, both turned out to erase, in brutal and absolute ways, people's rights, and people's lives, by the millions. So why were people so gullible? The German socialist Rosa Luxemburg in 1919 could see the path Lenin was embarked upon and called it 'a brutalization of public life: attempted assassinations, shooting of hostages, etc.' The German liberal Max Weber, writing in 1918, could also foresee what would become of Lenin's sociological experiment, saying it would end 'in a laboratory with heaps of human corpses.' Similarly, the British diplomat Eric Phipps wrote in 1935 that if Britain were to take Hitler'sMein Kampfseriously and literally, 'we should logically be bound to adopt the policy of a "preventive" war.'The dangers of a fascist turn were clear. The unlikelihood of success at even slouching toward a good society of those who took that turn ought to have been obvious.Utopian faith is a helluva drug.
