When the Incas had to transport heavy objects, they relied on manpower, often to the considerable sorrow of the men doing the powering (some 3,000 of 20,000 workers died dragging one particularly massive stone, according to chronicles)

Incan families paid their ‘taxes’ to the state by one member providing manual labor for the ‘state’. Though I don’t recall the exact time frame per year, I do remember it added up to less time than the average tax payer works for the state in modern USA.
