Saw this on tv tonight from Keith Olbermann.
The vast majority of the time he comes across as a fool to me, but at least this rant right there came across as authentic and understandable as a rationale for wanting to cover all people. How one might come to argue for it being a "right."
And so he gave the authentic argument, overflowing with Ethos and Pathos, if not necessarily Logos.
I still can't go so far as thinking of health care as being a "right" in the same way I consider freedom of speech a right, but I can say I am sympathetic to having more people covered.
The argument of cost does not have the same force, and frankly does not come across as authentically liberal. The authentically liberal argument would seem to say yes it will cost more to cover more people, and we should be glad to pay for it because we think it is the right thing to do.
