...The key words in Kara Balut's summation is "for those who can afford it".
No, the only way that the Canadian public system really works is to use the money for the big ticket diseases and conditions and care, from primary care through quaternary specialists.
And to clarify what I meant by "for those who can afford it"...
The US consumer has come to expect more that just good healthcare- the ability to be see any doctor at any time, TVs in hospital rooms with lots of cable channels, private rooms,etc. On the extreme end of the scale, I have worked with hospitals in the US that had concierge service where you could call and ask for special food anytime of the day, higher thread count sheets, comforters, etc.
In a socialized system, there are basic levels of healthcare that you are entitled to and your taxes/fees make that system free or available for a smaller fee. If you don't have an emergency or urgent condition, there may be a wait of a couple of weeks to see a provider and a similar wait for elective surgeries. If you want that extra level of service beyond what the social system offers, you can have private insurance. A 20 year old college student might be happy to be in a semi-private hospital room in exchange for free care. On the other hand, a 50 year old with a well-paying job might want the private room and they can afford the private insurance that will cover those items.
Keep in mind, that if you're on Medicare, it doesn't cover dental, vision or things like hearing aids. The same is true of most US group health plans- dental, vision and long-term care require additional insurance.
In the H&W forum, I'm offering advice to people in a lot of different countries. There's a big contrast in- for example, providing advice on getting an STD test in the UK, where I can just tell the person to make an appointment with the genito-urinary (GUM) clinic where they don't have to worry about the cost versus trying to find a place to send someone in the US who will have to pay $150 for a physician visit and another $200-300 for STD testing.
I used to refer people in the to Planned Parenthood because they have a LGBT program with sliding scale fees but this crowd in Washington seems determined to defund those programs in order to punish Planned Parenthood...but I digress...
This is really the underlying issue- that we also have two health systems in the US: one for those who have health insurance and another (underfunded) system for those who don't. What the ACA was trying to do was make it so that everyone had some form of health insurance and there was a basic level of service that everyone could depend upon.
