In one decade in the eighteenth century, according to the Swedish economist and historian Eli Heckscher in his book of 1932, Mercantilism, the French government sent tens of thousands of souls to the galleys and executed 16,000 (that’s about 4.4 people a day over the ten years…) for the hideous crime of importing printed calico cloth.
