people forget that nothing is for free. it is true that in many western countries: it is pre-pay. the monthly contributions from the people (and the companies they work for) make the system work. that's the core idea of socialism. people support each other, whether they like it or not.
they say it is overcharged and unfair. maybe. you might not be sick all-year round unlike your neighbour, but perhaps, in the future, you might need your health card. the hospital crew cannot drive you away because you are part of the system.
one thing is clear. the rich don't care about social welfare system. without the social safety net the poor are always the losers.
if i were to choose between a country that has a functioning social welfare system like denmark and one that has not, then i'd absolutely choose the former.
