This episode examines the mechanics of centralized state control and the price paid for building vast human systems, starting with the Inca Empire, a state that achieved incredible stability and scale without money or markets. The Inca achieved this by dictatorially centralizing an existing communal labor tradition, called mita, turning it into mandatory state conscription for infrastructure projects, the military, and other state needs. The logistical success was immense, demonstrated by Spanish reports of vast, overflowing state warehouses—a visible guarantee of abundance and a symbol of prestige that proved the state could guarantee provision and eliminate hunger. However, this system's reliance on centralized control of labor and resources, rather than market efficiency, presents a fundamental challenge to modern economic assumptions about stability and success.

The theme of central control is then traced to global trade and military logistics, where strategic commodities like salt and sugar became crucial state assets. The Spanish Crown's attempt to centralize profit by taxing Yucatan salt, for example, failed disastrously, making the salt too expensive to compete and creating logistical inefficiencies that defied logic. Conversely, the strategic importance of salt was recognized by Union military planners during the US Civil War, who specifically targeted Confederate saltworks to cripple the Southern war effort. In the 18th century, the immense wealth generated by sugar refineries in places like Bristol was entirely dependent on the brutal, centrally organized Atlantic slave trade, illustrating how a single commodity could fuel vast wealth and entrenched exploitation.

Finally, the discussion turns to the human cost when the state's power is absolute, from mercenary captains like Arnaut de Cervole holding the Pope hostage for a full pardon and protection money, to the horrific efficiency of 20th-century totalitarian regimes. Under the Soviet Union's Great Terror, bureaucratic quotas and simple ideological labels like "Polish" or "kulak" were used as deadly short-cuts for statistically motivated mass arrests and executions. Similarly, in Nazi Germany, the system was geared toward the systematic elimination of categories of "undesirable" people, with even doctors complicit in using crude biological criteria to identify victims for murder. The philosophical underpinning for such actions often came from a counter-Enlightenment thought that rejected universal human nature in favor of unique group identity, justifying exclusion and providing the intellectual soil for totalitarian control.
