Sure, healthcare can be super cheap as long as you stay healthy. What are you going to do if you get cancer? What if you break your leg in 5 places and need months of rehab? Just because you aren't sick now doesn't mean that healthcare is irrelevant.
I don't have specific statistics but in argentina the public hospitals that deal with cancer are decaying institutions and the people that I know have cancer use private insurance.
So didn't solve it either.
Im contesting the idea that public healthcare is what 1) lowers cost 2) guarantees good care
