Bullshit. Private companies develop most drugs. Furthermore, drugs that have been on the market for more than 7 years are no longer covered by a patent, so they are generally quite cheap.
Bullshit. Look up Enbrel and the shenanigans Pfizer pulled off to extend their patent. It's a life-saving medication for some people and it costs $1200 per month. They got WAY more than their R&D returned on investment and now they're padding their yachts.
Exactly what shenanigans did Pfizer pull off? They applied for, and received, a 2nd patent that continued the exclusivity for another 16 years.
But please, tell us what shenanigans Pfizer pulled off. And also, tell us whether there was much probability that a generic version would have become available.
Oh, and please tell us what was spent on R&D for this drug, and how much
profit was made in the first 14 years it was on the market.
