The FDA set standards for producing beef, but such rules can be difficult to enforce. When a giant like McDonald's tells suppliers that it will only buy beef that has been produced according to FDA standards, it can effectively enforce the rules. The sad part of this story is that more companies do not act that strongly to protect their customers. Because buyers collectively decide which company is successful and which fails, they theoretically have the power to force companies to produce the best products at the best price. Fear of lawsuits forces many companies to put more resources into defending their products.
Marketing has an even more profound effect on the relationship between businesses and consumers.
Some products mass-produced designer clothes for example are bought by people who are more interested in the image of the product than its basic qualities or price. These expensive products are an opportunity to show off how much a person can spend on personal items. At the other end of the spectrum are items advertised solely on the basis of low price. That is a practical concern for families with tight budgets, but the lowest-priced item may not be the best value. Something slightly more expensive may be far more durable or offer additional features that justify their cost.
