If the problem is that the majority of citizens can no longer afford medical attention because they can't afford medical insurance, the cost of providing some sort of assistance, would be far less than the cost of the loss in productivity as a consequence of general lowered level health of the people.
"Or that they must provide a job to everyone?"
Well they sort of do that already, they manipulate the economy so that as many people as possible have jobs.
I am referring to the ideal that everyone has a job and unemployment is almost non-existant, as the gov. gives you a job, no matter how crappy it is.
