Actually, that's false. I can assure you that having lived in Canada and having moved to the US because of health care, having options beyond "deal with it" when not getting any sort of care or service is wonderful. Single-payer is great if you are actually getting the care you need. But when it fails, you are left with little to no alternative.
What's worse is that because of the perception that single-payer is so great, people don't really push for real solutions to solve its many problems. People would rather stick their head in the sand and ignore the very real problems, pretending everything is ok.
Until then, we happily live here in the US where we get more services for less than what it would have cost in Canada.
