Why is this so difficult? We have free socialized schools, postal service, roads, police, fire departments... What's so different about health care?
We need government provided health care for the same reason we need those other government provided services. They're necessary for the proper functioning of society, and cannot be efficiently dealt with by many different entities.
I don't really care what it costs. If taxes need to be raised to make ends meet, then so be it. Raise taxes. If some rich people can't bear to part from another 1% of their money, screw 'em.
I think my favorite conservative argument against health care is that people should be responsible for themselves. Because, if you work a minimum wage job with no benefits, you deserve to die.
It's time we joined the rest of the first world, and start giving a shit about our citizens.
