economic systems that are the most important to a democracy are characterized by ownership of private property, freedom of enterprise, free prices, private motive and limited interference of government. The market is left to the forces of demand and supply with the government only interfering as a regulator.
In this case we can infer that, by decreasing the demand (population), the supplying of clothes increases, generating a decrease in the prices of the products, thus causing the demand curve to move to the left, causing the bidders to reduce production costs.
War was comming and they wanted to attack on their own terms!!
