Production systems are designed to take account of market indicators that determine whether goods produced will sell, rather than the indicators of human requirements. Sales promotion has become the dominant force, relegating market research to providing necessary data. Producers rely on sales promotion to sell more of the same type of products to the same limited market regardless of need.
For instance, huge amounts of advertising money are used to sell forty different kinds of soap.
Increased use of sales promotion is needed to sell more products to more people in direct relationship to need.
