Reasonable Profit

Businesspeople must secure a reasonable profit based on their own business philosophy, while treating their customers with consideration. This is an important social responsibility that contributes to overall social prosperity.
To engage in this desirable form of business, rather than negotiate pricing with customers and lowering the price in an opportunistic way, businesspeople should set the most competitive price possible based on careful analysis. Instead of offering discounts, the seller should convince the customer that the price is fair. "That retailer never offers discounts, but they do provide valuable service over time that is better than a discount, and they are very kind to their customers." That is the logical and right way to do business.
