If you've lived in a country with universal, free healthcare you only get an idea what it would be like without it when you travel. The need to get medical insurance is an eye opener.
We all have experience of insurance companies through household and car insurance and know how weasily they get when you need to claim - am I actually covered for this? I'd hate to be worrying about that when I'm driving to A&E with my child.
I doubt that any democratic country has ever taken the decision to reverse universal healthcare once provided, it's value to the individual is just too high - politician tinker with it at their peril.
The US's position is strange to an outsider - it seems to be a problem with the word 'social' rather than the principle of healthcare; it's a totem of rightwing machismo that anything called 'social' is actually communism in disguise so a line can be drawn.
Perhaps liberal (another word generally regarded as a 'good' thing here but is perjorative in the US) politicians should rename the other things the state provides as services for all, Social Education, Social Defence, Social Highways, Social Street Lighting.....
