"I find that incredible," Erskyll declared promptly. "Twenty million people, held in slavery by ten thousand! Why do they stand for it? Why don't they rebel?"

"Well, I can think of three good reasons," Douvrin said. "Three square meals a day."

"And no responsibilities; no need to make decisions," Degbrend added. "They've been slaves for seven and a half centuries. They don't even know the meaning of freedom, and it would frighten them if they did."

"Chain of command," Shatrak said. When that seemed not to convey any meaning to Erskyll, he elaborated: "We have a lot of dirty-necked working slaves. Over every dozen of them is an overseer with a big whip and a stungun. Over every couple of overseers there is a guard with a submachine gun. Over them is a supervisor, who doesn't need a gun because he can grab a handphone and call for troops. Over the supervisors, there are higher supervisors. Everybody has it just enough better than the level below him that he's afraid of losing his job and being busted back to fieldhand."

"That's it exactly, Commodore," Degbrend said. "The whole society is a slave hierarchy. Everybody curries favor with the echelon above, and keeps his eye on the echelon below to make sure he isn't being undercut. We have something not too unlike that, ourselves. Any organizational society is, in some ways, like a slave society. And everything is determined by established routine. The whole thing has simply been running on momentum for at least five centuries, and if we hadn't come smashing in with a situation none of the routines covered, it would have kept on running for another five, till everything wore out and stopped. I heard about those missile-stations, by the way. They're typical of everything here."

"That's another thing," Erskyll interrupted. "These Lords-Master are the descendants of the old Space-Vikings, and the slaves of the original inhabitants. The Space Vikings were a technologically advanced people; they had all the old Terran Federation science and technology, and a lot they developed for themselves on the Sword-Worlds."

"Well? They still had a lot of it, on the Sword-Worlds, two centuries ago when we took them over."

"But technology always drives out slavery; that's a fundamental law of socio-economics. Slavery is economically unsound; it cannot compete with power-industry, let alone cybernetics and robotics."

He was tempted to remind young Obray of Erskyll that there were no such things as fundamental laws of socio-economics; merely usually reliable generalized statements of what can more or less be depended upon to happen under most circumstances. He resisted the temptation. Count Erskyll had had enough shocks, today, without adding to them by gratuitous blasphemy.
