Both systems have flaws? True, but it’s a false equivalence. There’s a reason why there’s only one country in the world where insurance company CEO’s have to hire security to walk around in public.
Not really. At the end of the day, in both systems, the person paying for the healthcare decides what healthcare options are available to the patient. In the US, the patient themselves (or their insurer) is paying.
In other countries, it’s often the health service itself that is paying.
Don’t get me wrong, I believe the single payer system is infinitely better, but for a small number of people, it will lead to worse healthcare outcomes.
