In "Looking Backward", a non-violent revolution had transformed the American economy and thereby society; private property had been abolished in favor of state ownership of capital and the elimination of social classes and the ills of society that he thought inevitably followed from them. In the new world of the year 2000, there was no longer war, poverty, crime, prostitution, corruption, money, or taxes. Neither did there exist such occupations seen by Bellamy as of dubious worth to society, such as politicians, lawyers, merchants, or soldiers. Instead, Bellamy's utopian society of the future was based upon the voluntary employment of all citizens between the ages of 21 and 45, after which time all would retire. Work was simple, aided by machine production, working hours short and vacation time long. The new economic basis of society effectively remade human nature itself in Bellamy's idyllic vision, with greed, maliciousness, untruthfulness, and insanity all relegated to the past.
