Journalist: To reconcile the need for profits sufficient to support new drug research with the moral imperative to provide medicines to those who most need them but cannot afford them, some pharmaceutical companies feel justified in selling a drug in rich nations at one price and in poor nations at a much lower price.
Evidence
A nation with a low average income may still have a substantial middle class better able to pay for new drugs than are many of the poorer citizens of an overall wealthier nation.
Conclusion
The practice of selling a drug in rich nations at one price and in poor nations at a much lower price is unjustified.
Evaluate
The argument assumes that it is more important to consider the ability of an individual to pay for a drug than the ability of the average citizen within a country to pay.
