Caramel,
I live where many Canadians spend vacation time or live part time. They LOVE their healthcare and have no complaints. That is my personal experience when talking to them about it.

I also know several folks who live in the UK who also LOVE their National Health System, which ironically used US finances to fund it initially. Here is a link to the NHS site: http://www.nhs.uk/Pages/HomePage.aspx .

Even if those two national healthcare systems didn't work, I see no reason why a country like the US could not make a system that works well and is affordable for all. For one thing, Medicare and Medicaid could be discontiued because those covered under them would be moved to the national healthcare system.

Now that healthcare has been diluted to become more exclusive, and something less meaningful and less helpful, and insurance is no longer where investor's make a boatload, my hope is that a national plan is created. I'm not holding my breath, just hoping
