Society obviously must have farmers before it can eat, foresters, fishermen, miners, etc., before it can make use of natural resources; craftsmen before it can have manufactured goods; and merchants before they can be distributed. But once these exist, what need is there for government directives, mobilizations of labor, or periodic assemblies? Each man has only to be left to utilize his own abilities and exert his own strength to obtain what he wishes. Thus, when a commodity is very cheap, it invites a rise in price; when it is very expensive, it invites a reduction. When each person works away at his own occupation and delights in his own business, then, like water flowing downward, goods will naturally flow forth ceaselessly day and night without having been summoned, and the people will produce commodities without having been asked.
