I don't pay through my nose for healthcare. According to a quick Google search, it seems to be about what the average US resident pays (while I'm above average in income for my country). For that price, I don't ever have to worry about going to a doctor or hospital. I'm feeling sick - I go to the doctor. I have a toothache - I go to the doctor. I think I broke my finger - I go to the hospital, wait a few hours, and learn that everything is alright. I can't imagine having to wonder if the visit is really necessary, because I need the money. I don't want to have to choose between health and money. For me, this is comfort.
Additionally, I have friends with chronic diseases. They cannot emigrate to the USA, because they couldn't pay the medicine. That doesn't sound like a first-world country to me, where you cannot afford to treat your sickness, even though you've got skills and a paying job. That sounds like a bad dystopian movie.
