Chapter: The Use of Spies 13.1

Translation:

Sun Tzu said: Raising a host of a hundred thousand men and marching them great distances entails heavy loss on the people and a drain on the resources of the State. The daily expenditure will amount to a thousand ounces of silver. There will be commotion at home and abroad, and men will drop down exhausted on the highways. As many as seven hundred thousand families will be impeded in their labor.

Commentary

War is very expensive. It costs in terms of lives, even when there is no fighting. It costs in the patience and support of the people at home. And it costs enormously in money.

That cost is paid for long after the war is ended, even if you are the victor. You should understand the cost before you go to war and as you continue each day of warfare.

Competing is also expensive in business. The cost of marketing, PR and sales can easily be far more than the cost of creating the product or delivering the service. When deciding what to offer, take all such expenses into account.
