Here you go. This is why they charge so much. YOU EVER CREATE A PRESCRIPTION DRUG OR VACCINE??? You ever do a fucking thing to make the world better at all??? Of course you haven't.
Now I know what you are going to say: "Well what about 'isn’t just a reflection of its R&D cost'"????
Thing is that some drugs pan out and some don't. The ones that don't pan out can cost 100,000s or 1,000,000s of dollars they don't get shit back.
The technology you need to even start trying to make drugs is expensive as fuck.
So yeah, in the end PRIVATE INSURANCE pays for drugs. If it were not for this then a lot of good drugs would not be invented. The assholes selling generic didn't do the research but they benefit from it.
