A couple of answers.
1. Canadian health care is not perfect by any stretch. People die while waiting for health care sometimes - just as they die without health care in the US. However, most Canadians I know wouldn't consider trading it for the American system and in fact are horrified by the stories like the ones we've heard here. Health care is rationed everywhere in the world - either by availability or by ability to pay. I prefer the triage method we use.
Would I spend my money to jump the line if one of my kids were ill - in a minute if I thought it would help. However, I'd be one of the few who could afford to do so and I'd recognize it as a very self-serving action, not a vote to change systems.
2. Our UHC does not cover dental care. Good jobs include dental insurance. Low paying jobs generally do not. However, it isn't prohibatively expensive to middle income people.
3. Do Doctors get paid enough to be creative? My dad was a doctor who was practising when UHC come in. He thought it was brilliant for doctors and patients. He defended it always despite many attempts by American companies to recruit him to the US. My sister is a doctor who cares deeply for her patients and works her fingers to the bone for them. She and other friends who are doctors would be deeply offended by the idea that more money would make them better doctors.
My daughter (95% average in Gr 11) wants to be a doctor. She'll have to work very, very hard to be accepted despite very good grades and lots of other talent. My sister says that one of their problems as doctors is to figure out how to weed out the merely academically brilliant to get to the compassionate, caring people who are also academically brilliant.
