I'm glad this article provides real data and solid analysis to back my intuition.
A patient and doctor don't care if a treatment costs $1 or $1million if they aren't footing the bill. You need someone in the system to say that treatment is too expensive, you cant have it.
That'd be triage, and I don't think it's the insurers' business – or even the doctors', unless they're in a field hospital in a war zone.
The article argues that prices are too high, because of monopoly power. Get prices down and triage won't be necessary anymore.
If there is nobody to say no to $1 million dollar aspirin, that is how much you pay.
Money is finite, so that means people dont get care. Care is always rationed.
