He edited his post. It said something a bit different originally. But to your point, drugs are a pretty different animal. A lot of drugs have a relatively niche market. Take the Hep C cure, for instance. The company that sells it charges something like $80,000 for it, which seems exorbitant to a lot of people.
But how much did it cost them to develop that drug? To get it through the FDA approval process? Their breakeven price on that drug is definitely in the tens of thousands per dose, before you get to any profit. Which means that at a minimum, they're charging $10,000/dose. In the case of movies, sure, i'll pay for netflix because it's more convenient than torrenting, because Netflix costs $10. If Netflix tried to raise their prices to $10,000/month, i'm going to start torrenting again.
