In North America, the Oligarchy maintains power for three centuries until the Revolution succeeds and ushers in the Brotherhood of Man. During the years of the novel, the First Revolt is described and preparations for the Second Revolt are discussed. From the perspective of Everhard, the imminent Second Revolt is sure to succeed but, from the distant future perspective of Meredith, we readers realize that Everhard's hopes were to be crushed for centuries to come. The Oligarchy are the largest monopoly trusts (or robber barons) who manage to squeeze out the middle class by bankrupting most small to mid-sized business as well as reducing all farmers to effective serfdom. This Oligarchy maintains power through a "labor caste" and the Mercenaries. Labor in essential industries like steel and rail are elevated and given decent wages, housing, and education. Indeed, the tragic turn in the novel (and Jack London's core warning to his contemporaries) is the treachery of these favored unions which break with the other unions and side with the Oligarchy. Further, a second, military caste is formed: the Mercenaries. The Mercenaries are officially the army of the US but are in fact in the employ of the Oligarchs.
