principle of justice

Please share your research, experience, and thoughts:   Using the ethical principle of justice, determine whether health care in this country should be a right or a privilege. Are the uninsured and the insured “unequals” that should be treated according to their differences? Does the type of health insurance that one has also create a system of “unequals”? If so, are the unequals being treated according to their differences?  Specifically, what should health care providers “do” to positively contribute to help foster a healthier society?  Your research, experience, and opinion are welcomed in this forum.
