Drug costs are also a small percentage of the national health expenditure, which is dominated by procedures delivered in hospitals and outpatient clinics. I don't accept the logic you're using for drugs, but we don't reach that question until we figure out why the single largest health expenditure in the United States has no impact on health insurance costs, which are the primary way Americans interface with the health insurance system.

If that expenditure does impact health insurance costs, then the rebuttal given above about increasing the supply of doctors not improving affordability fails.

If you google [National Health Expenditure spreadsheet], there's an annual spreadsheet that has includes an incredible amount of detail about where we spend money, broken down in a variety of different ways.
