Passage Summary: A journalist argues against charging different prices for medicine based on a country's average wealth, noting that there are wealthy people in poor countries and poor people in wealthy countries.

Conclusion: The practice of selling drugs at higher prices in rich nations and lower prices in poor nations is unjustified.

Reasoning: National averages hide individual realities, as poor nations have middle-class citizens who can afford drugs, while rich nations have poor citizens who cannot.

Analysis: The journalist is attacking the use of 'national average income' as a proxy for an individual's ability to pay. To justify the conclusion that this pricing is 'unjustified,' we need a principle that prioritizes individual financial status over national averages. Look for an answer that suggests a pricing system is unfair if it fails to account for the actual economic circumstances of the individuals buying the product. The argument essentially claims that the 'moral imperative' should be applied to people, not to borders.
