Met an RN a couple days ago, told her about my cheap healthcare plan (daily spinach and fruit smoothies, multi grain cheerios with their 9 embedded vitamins 100% daily recommended, variable protein sources with constant physical activity, lots of untreated water if possible, staying on the move and paying attention at all times so as not to get injured). We discussed socialized medicine of other nations, and she seemed to show an aversion to it. Her argument was that not as many people would want to get into medicine since they wouldn't be paid as much. She works in ER so the first thing I think of is trauma which is different than caring for a lethargic citizen decaying away because of their own habits.
But privatised healthcare generates the fear of the high medical bill, and this could incentivize people to exercise caution (pun? kinda). I personally would not prefer to give doctors all my money in the final few years of a sedentary life spent carelessly.
