Richter's novel advances a very different explanation for socialism's "moral decay": The movement was born bad. While the early socialists were indeed "idealists," their ideal was totalitarian. Their overriding goals were to engineer a new society and a New Socialist Man. If this meant treating workers like slaves - depriving them of the freedom to choose their occupation or location, forbidding them to quit, splitting up families without their consent, and imposing draconian punishments on dissenters - so be it.
