When socialised medicine and national insurance are portrayed as waiting lists and death panels, it is like saying that all of the US system is like my sister's experience. She worked for many years in a high paying job and had part of the costs of her insurance deducted from her pay. When she was diagnosed with breast cancer, she had to give up her job to qualify for charity treatment and Medicaid because her insurance didn't cover the treatment she needed.
Don't you realise there are people who never get elective surgery in the US even when they have insurance? Don't you think that there are people who wait over 3 years for hip replacement in the States because they have no way of paying for it?
You're right. This needs to be done right. When NYS started offering Family Health Plus, it was not available to anyone with even the barest minimum of coverage. So, people like me without drug coverage were screwed. This isn't a time for half-measures.
If you focus on exaggerated horror stories about government provided healthcare or insurance, then you deserve to be scared. There are plenty of good examples of how the systems work well in both Canada and the UK, and plenty of examples from other countries where people see healthcare as a human right.
