Sun Tzu

When an army is nearby, it can cause prices to rise. This can be a problem for the local population, as higher prices can make it difficult for people to afford the goods and services they need, leading to a decrease in their overall wealth and well-being. Sun Tzu is emphasizing the negative impact that an army can have on a community, and the importance of considering the effects of military action on the people living in the area.

On the other hand, a business with high overhead causes prices to rise, impacting people's purchasing power.

A business might have a large amount of fixed expenses, such as rent, utilities, and salaries, relative to its revenue or sales. This will put pressure on the business to raise prices in order to cover its expenses and remain profitable. If the prices of goods and services offered by a business with high overhead increase, it can impact people’s purchasing power, or their ability to buy the things they need or want. This can be harmful to consumers who may not be able to afford the higher prices.
