“How is the seller supposed to know what is good for the consumer and what is bad?” Sometimes in business this issue has been neglected, since the primary goal of the seller is to accumulate profit, to increase their sales so regardless it will be or good or bad the issue is being diverted t the fact that they are geared toward increasing sales volume. I wish that despite of the aim to accumulate their earnings most businesses are ought to also operate in ethically sound business . Try to consider the welfare of the consumer. There are some codes of conduct that every business are deemed to be followed.
