This is not an interesting conversation honestly.
Some Americans think that the US Healthcare way is “the right way but Slightly Off-Track(tm)” and will not be suaded.
You asked a direct question, though, to what extent do social services exist.
Social services exist to ensure that we all have a decent foundation on which to conduct our business of living.
For some that will be as you say, providing basic food and housing. In fact in Sweden food is given to children for free in school; however in the UK it is only poor students that get it.
In Sweden water is free, in the UK it’s charged but it’s a utility that cannot be turned off.
Everyone draws the line somewhere else, but the basis is meant to be that we have a solid foundation.
Unexpected medical expenses shouldn’t decimate a household economy for a decade, it doesn’t matter how unprepared the household is. But this is my personal feeling.
In addition: tying health insurance to employment and having at-will working conditions strikes me as ensuring compliance/docility in the work place, which I don’t believe in.
