I love our Medicare system (Canadian) because it creates a peaceful feeling of reassurance. You show your Medicare card and you are good to go, no paperwork, no bills, nothing. It's hard to explain that feeling, the hospital is not a scary place, it is a safe place. It's there to help you. You just go to the doctor when you are sick, no big deal.
On average, we pay roughly 30-40% Income Tax. The less you make, the less you are taxed. If you make less than $38,000 in my province, you would pay something like 24% (15% federal tax + 9% provincial tax - http://www.cra-arc.gc.ca/tx/ndvdls/fq/txrts-eng.html). And if you make more you get taxed more, but it's reasonable.
Honestly, when you grow up here, you just get used to it. It comes off the paycheck just like retirement savings and employment insurance, and you don't think about it.
I'm a proud Canadian, equal healthcare for everyone is a value we share and I think it's worth paying for.
When I add together my taxes plus the health insurance premium that comes out of my paycheck, my net take home is probably less than what it would be in Canada. Sure I have the choice to not pay for health insurance, but that's an illusory choice. I've got a wife and a kid--I'm not going to opt out of health insurance.
