Just to weigh in, I am one of those cold, unfeeling individuals that believes that if someone can't pay for a medical treatment (or the insurance that covers it), then they should do without it. There are myriad things in society that the wealthy have more/better of than the rest of us--including basic needs like food, clothing, and shelter; I don't see why medical coverage should be any different.
People talk about health care as a "right", but that's contrary to the fundamental concept of what a "right" is. A right is something that you have naturally, not something that is conferred upon you. A right is not something that the govenrnment grants; it is something that the government should not inhibit. So when the Declaration of Independence talks about "a right to life", this doesn't mean that the government has a responsibility to ensure that your life continues; it only means that the government has a responsibility to not deprive you of your life.
There is no right to health care, just like there is not a right to have food, clothing, or shelter. People are responsible to provide for their own needs; it is not the government's responsibility to provide for them. Now, I am fully in favor of individual charity and privately funded charitable organizations that seek to meet these needs for those who cannot; however people should have the choice to decide whether, when, and how to contribute.
