It's worth pointing out that for the vast majority of people doctors != insurance. The payer is not the provider.

The refrain of "people like their health insurance" deliberately conflates the two. People like their doctors, not their insurance. Doctors accept multiple insurance companies.

> Doctors accept multiple insurance companies.

Some do, but not all. One of my providers takes exactly one insurer, which I do not have, so pay out-of-pocket.

Luckily most insurance companies allow you to submit receipts to receive credit towards your deductible.

And to top it off, old people (actual old people) are already using socialized medicine. They aren't using private insurance (or, if they are, it's used to cover coinsurance/deductibles).

health insurance != heath care
