Let's not forget some people look at curing people suffering form disease as just an Investment?
These biomedical companies are in business to make shareholders rich--it's just about the money. Maybe medicine has always been just about the money?
The prices most drug comapnies charge for their latest drug seem outrageous? Want a jaw dropper--look into Biomarin drug prices. Read their prospectus--it reads more like a hedge fund, rather than bio company. Oh, and one of their buildings is sitting on the San Andreas Fault. Found that last sentance interesting--I guess lawyers were being proactive?
But then again, I'm for government funded research, I would like to outlaw forprofit Insurance, and I have become a huge skeptic of modern medicine.
(As a side note; If you noticed your generic drug is not dropping in price like it did years past, you are not loosing your mind. Supposedly, large drug companies(companies whose drug patents are expiring, or expired) are buying smaller generic drug companies, and either shutting down the operation, or keeping the generic price, of the newly aqquireed company, artificially priced high. I believe congress, or the FDA is looking into this slick business tactic? It's completely legal now.)
These aren't cheap to mass produce.
Edit: Not the best source I could find, but this cites costs (not at scale) :
