There hasn't been a good example of a single payer healthcare system. I have family in Canada and follow UK politics regarding NHS and as someone who has had to have non life threatening but very painful urgent care done within hours while seeing my family suffer for months for things that can and did kill them to get even the most basic diagnostics done. No thanks.

If we restricted it to things like broken bones and the most basic healthcare imaginable sure. But we always want to spend millions on saving one person and we simply can't afford that nationally for every single person walking on our dirt. Triage universal health care sure, but that's considered heartless so I just vote no universally.
