It appears that pharmacy managers have decided that spending 5x as much as a French patient does is stupid:

Hallelujah. I never thought I’d see the day that I’d praise an insurance company. But the proverbial Atlas just shrugged.
Insurance company pharmacy benefit managers, who have apparently had it with drug companies charging American consumers ridiculously high, and ever-increasing, prices for prescription drugs, are starting to say “enough.”

At the top of the list is my asthma drug, Advair.

Some big insurance company pharmacy benefits managers are simply no longer permitting their plans to cover Advair. Or at best, they’ve relegated Advair to the lower “third tier,” which means the patient has to pay so much of the price that they simply won’t buy the drug at all.
As a result, Advair sales plummeted 30% this year in the US.

(emphasis mine)

It’s a battle between two groups of parasites, and I hope that there is a way for both of them to ose.

Come to think of it, there is, it’s called Single Payer, bitches.
