Speaking as someone who has benefited from the Canadian Health Care system, I have to say that its worth the tax dollars that would be spent on it.
I've had some procedures done due to injuries from a car accident, as well as a lengthy hospital stay (4 months) that would have bankrupted my family, but it was free. The hospital I was in is considered one of the best in Canada and western North America (Edmonton General Hospital), so quality of health care wasn't in question.
Imagine the amount of worry and stress you wouldn't have if you found yourself having to go to a hospital and not worry about how much its going to cost you.
Yes, there are some downsides to Universal Health Care, one of them being wait times. The sickest and most hurt will get seen first, that is the first basic thing about Triage. Stop being selfish. If waiting in line is that much of a problem for you, There will always be places where you could be seen right away, but it will cost you money, which is the biggest issue isn't and the reason Universal Health Care is being batted around.
The US claims to have the best health care system in the world, yet its only available to those that can afford it, which, lets be honest here, isn't everybody. Universal Health Care would eliminate that.
The right to be healthy and to receive treatment when we are sick and injured is just that, A Right. It should be available to everyone.
