This essay discusses differing perspectives on the appropriate level of government intervention in markets from four authors - Cunningham, Green, Friedman, and Pertschuk. Cunningham and Pertschuk believe consumers are relatively weak due to a lack of knowledge and that low incomes cannot match sophisticated marketers, so they support more consumer protections. Green and Friedman view consumers as stronger and prioritize efficiency, with Green supporting only safety and economic regulations while Friedman believes the FDA's drug oversight is beneficial.
