Nationalized is a short fiction work about the possible outcomes of nationalized healthcare. Generation Joshua has linked to it on their Facebook page, and I also encourage you to read it! I think it may be a great tool for encouraging awareness and involvement on this all-important issue.
Having had a lot of contact with the current private healthcare system, I will be the first to admit that it is by no means perfect, however I cringe to think what I and my family may have to go through if it were nationalized. The world of medicine is not cut-and-dried. It is not a world of if 'A' then 'B' - it is a world of "what is 'A', and what should 'B' look like". Any non-traditional illness needs to receive non-traditional treatments, and there are very large concerns that anything non-traditional may indeed be significantly limited - and you wouldn't believe how many people need that sort of help!
Anyhow, enough of my pontification, go and read the story, and I hope you think about it.
