They key point is that healthcare insurers, pharmacy benefit managers, pharmacies, and healthcare groups are all owned by one holding company which benefits when prices go up. People think that the insurer will try to keep costs down, but in fact, if prices go up they can charge more for insurance... the only way they can keep increasing shareholder value is for prices to go up. So they do, and by owning the entire chain they can force that to happen. There is no market.
Insurers will not negotiate prices lower, it is against their interests!
