I think its all of the above.
Its a privilege because well all countries dont have what we have. technology facilitates etc.
I also think in certain cases it should be restricted.
its a right because we are a first world civil country. People should die in the streets because they are the wrong color or income or gender or sex etc. Now of course this has restrictions also
its a responsibility because a person should make decent choices and be willing to set aside money to help insure good care. You eat KFC 3 times a day every day, drink every day, smoke every day and do heroin, well dont be surprised if the best care isnt just thrown at you and you arent rushed to the front of the line for lipo-section, a new heart, lungs, liver and a face lift lol
and its other because its a mix of these things and others. It cant JUST be a right, just like your current rights are just rights, they are responsibilities and privileges.
