What is your ideal healthcare system?

Hey, rather than talk about negatives etc on healthcare, I'm wondering if you had all the power to change everything, how would you set up health care in the US?

I'm from NZ, we have it covered by the govt (so we pay taxes instead of health insurance basically) which has its issues (happy to talk about those issues if you have questions) but this means how health care and insurance works for you guys is totally alien to me. I hear and see online a bunch of people complaining, and obvs the left want a single pay model, but what would be the 'best' way to set it up from a conservative POV?

Wishing you all the best from Aotearoa, New Zealand Cheers
