Marketing benefits society in general by improving people’s lives in two ways. First, as we mentioned, it facilitates trade. As you have learned, or will learn, in economics, being able to trade makes people’s lives better. Otherwise people wouldn’t do it. (Imagine what an awful life you would lead if you had to live a Robinson Crusoe–like existence as did Tom Hanks’s character in the movie Castaway.) In addition, because better marketing means more successful companies, jobs are created. This generates wealth for people, who are then able to make purchases, which, in turn, creates more jobs.
The second way in which marketing improves the quality of life is based on the value delivery function of marketing, but in a broader sense. When you add all the marketers together who are trying to deliver offerings of greater value to consumers and are effectively communicating that value, consumers are able to make more informed decisions about a wider array of choices. From an economic perspective, more choices and smarter consumers are indicative of a higher quality of life.
