We’re talking about a drug here, not brain surgery. It’s price is high in the US because of patent rights, not because it’s expensive or necessarily hard to produce.
You're "dead" wrong on that. It’s price is high in the US because it costs about a billion dollars to complete all of the testing required to get a new drug approved by the FDA. Then, they can only recover that cost during the time of the patent coverage, because the patent is required to give sufficient information for anyone else to produce it.
