Adding to this, another reason I hate private insurance is the concept of networks and claims. It doesn't really matter what insurance you have.

I have an upper-middle tier PPO, and still two doctors offices have turned me away because they don't accept it... completely boggling.

Not to mention the herculean efforts you have to put forth to synchronize your personal health records / documents between offices and systems because everyone is using different nightmarishly siloed systems (although in theory will start improving eventually thanks to the FHIR standard, but still change in healthcare is SLOW).

If it was like that between US states, I would understand. But between offices up the road from each other? Give me a break.

In my opinion, the only thing we have that works well is Planned Parenthood, which I've used a couple of times and attest that they are just phenomenal. Unsurprisingly they also happen to be a non-profit. For-profit does not work for everything, and thinking it does (or should be a requirement of capitalism) is completely lacking in imagination and empathy.
