Preamble to the Constitution:
"We the People of the United States, in Order to form a more perfect Union, establish Justice, ensure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."
Seems to me the general Welfare would include universal health care as a right, not a privilege. And then there was the Declaration of Independence:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
Now how can you enjoy "Life, Liberty and the pursuit of Happiness" without your health? Case closed.
