A third of every dollar pays for the fight, not the care.

Here is a number worth sitting with. By one recent estimate, roughly a third of every American healthcare dollar goes not to care but to the fight over who pays for it — coding, billing, prior authorization, appeals, denial management. There is a two-hundred-billion-dollar industry whose entire purpose is to move a bill back and forth until one side gives up.

I’ve spent twenty years at the boundary between the people who deliver care and the people who build the systems around it. From that seat, the tell is unmistakable: we don’t reward the practice with the best outcomes. We reward the one that handles the paperwork best. A large health system keeps a floor of people whose whole job is winning claims one at a time. The independent physician does eight prior authorizations a day, alone, between patients. The paperwork isn’t friction on the business of medicine. It is the business.

Call it what it is: extraction. Extraction capitalism grows by inserting itself between two parties who need each other and taking a cut of the distance between them. In most industries there’s a natural ceiling — customers eventually notice the toll. Healthcare removed the ceiling, because the party paying (an employer, a plan) is not the party receiving (the patient), and neither can see the other clearly. The gap between them is dark, and the dark is where the margin lives.

Here is why this matters more now, not less. AI is about to make the extraction machine cheaper and faster — more denials, more automated appeals, more sophisticated ways to move the bill. Point AI at the fight and all you’ve built is a better weapon in a war that shouldn’t exist. The question every builder in this space is actually answering, whether they say it out loud or not, is a single one: are you making the extraction more efficient, or are you making it unnecessary?

Care cannot run on extraction capitalism, and the reason is structural, not moral. Every dollar the machine earns is a dollar subtracted from care, and the machine is designed to grow. You cannot align an incentive that only wins when care loses.

I’m not writing this to be cynical. I’m writing it because the alternative is buildable, and I spend my days building pieces of it. The rest of this series is about that alternative — what actually replaces the toll booth. It starts with the one word the extraction economy can never fake: accountability.
