OK, so before @zelmo1234 accuses me of using words to act superior, let me explain regional pricing. It's really simple, big pharmas, and by that I mean those who sell internationally, price pharmaceuticals by region. They will sell the same products cheaper in mexico and Canada than they will in the US. Why? Because the government protects them and allows it.
It's also called variable pricing and price discrimination. See, for example, What's Fair About Price Discrimination In Pharmaceutical Markets: "The companies want a system where they can charge different prices in different markets—whatever prices local markets will bear, without product leaking back from low-price to high-price marketplaces. Pharmaceutical companies can advance this goal by selling medicines at a discount, perhaps even a very steep one, in developing countries, while promoting regulations barring re-importation of these drugs to the U.S."
So it has nothing to do with "It sounds like bleeding heart libs want to give away these new drugs to poor countries at below cost." Or "hurting American companies and American employees." These companies, with the help of our government, are screwing Americans.
