Not true Spiker.
I have a friend who was quite high up in Novartis. The drug companies are amongst the most secretive in the world. What you see on the stock exchange is a very small part of the real companies. The profits are astronomical and as DC says the R&D costs are a complete smoke screen, all placed in the public side of the businesses to make their profits appear smaller.
They are able to blackmail governments, and they do. In the UK, our system is like Australia, we pay a prescription for the drugs, i.e. about $15, we pick up the rest of the cost in tax, so it isn't exactly free. When the drug companies have a patented medication it is hard for our government to negotiate on price, because the supplier can just say fine, tell your tax payers that you are going to let them die. They pay up.
It's time to reduce the patent life on drugs to say five years.
