I live in such a country and private insurance exists here, still finds ways to screw over customers. We need more CEO murders

It does. Basically all countries with universal healthcare also have a private healthcare sector. It is another ironic fact that countries with universal healthcare has more freedom of choice than people have with the American healthcare system.

In America, we don't learn from watching others. Hell, we don't even learn from our own mistakes.

Come to think of it, we barely even learn in the first place.

It does, in the Netherlands (my country), we have universal private healthcare.

We used to have universal public/singlepayer, but decades of liberal governance caused it to be privatised.

It does, and it's the first step in destroying national health care.

Yeah, and it's a scourge in those places too
