With private healthcare system, the difference will be that private company will be telling you to eat 5 vegs a day, then they will require that you take a photo each time you eat a veg and so on and if you don't you'll be left with nowhere to go for help. No thank you. I get that national health service is mostly rubbish, but it's better than nothing and if you are poor, it's your only chance and you can always have an option to go private.
