Why not, Peter? Let me start with "We hold these truths to be self-evident.." In other words, our nation is founded on self-evident basic rights which include life, liberty, and pursuit of happiness. Access to health care is an existential need, like access to food, and no nation constituted on self-evident basic human rights ought to leave out access to health care, which otherwise is limited to those who can afford it. Universal health care also is an ethical and moral imperative sunk deeply in the foundations of all Abrahamic religions; healing was a fundamental work of Jesus of Nazareth, as you likely are aware. Feeding the masses, and healing the afflicted. Jesus did these as an example to all of us.

From a practical standpoint, universal healthcare makes economic sense because only a healthy culture is productive. It makes social sense because a healthy society is a more inclusive society and a happy society.

I'm interested to read your case for the opposite premise.
