It’s not a lose for the consumer who needs Sovaldi but can’t afford its true cost of $1,000 a pill with a total treatment cost of $84,000.
It’s a loss for the consumer in the long run because the pharmaceutical company has no incentive to come up with a cheaper drug or lower the costs on the existing one. The insurance companies don’t lose (they never do) because they get to raise the rates on everyone, even people who don’t use pharmaceuticals.
