Price difference may be a valid argument. On the other hand in my home country we had some big pharmaceutical companies (compared to the size of the country) exporting drugs world wide. I thought that for example the pain killers I knew as I child would be used everywhere on the world. When I moved to Germany I realized that I was wrong. There are tons of different drugs for the same purpose with the same ingredients sold by different producers. Therefore only becasue you in the US buy some expensive - and highly addictive - pain killers you are not automatically financing the R&D of pain killers sold in Europe by Europian companies to the Europian people. Let me be a smart ass and improve your calculation: 45% of drug revenue is generated by 5% of earth's population: 45% / 5% = 9 but you do not compare this number to 1 but to 55% of drug revenue is generated by 95% of earth's population: 55% / 95% = 0.58 So a US citizen spends 9 / 0.58 = 15.54 more on drugs as a non US citizen. Even if price difference is a valid argument, this number is still too high.
