As marketers increasingly develop marketing programs tailored to certain target market segments, some critics have denounced these efforts as exploitative. For example, the preponderance of billboards advertising cigarettes, alcohol, and gambling in low income urban areas is seen as taking advantage of a vulnerable market segment. Some would answer these critics by saying that targeting and positioning is critical to marketing and that it is condescending to assume that certain groups of consumers are not mature enough to make up their own minds about what they purchase. How do you feel about this issue?
