It's the billing afterwards that's the issue.
Aussie healthcare is the best I've seen (and I've seen a few). Basically free, with more speed or better care (or whatever) if you want to pay for it. Health insurance is like US$75 a month and not tied to employment.
Absolutely anyone who’s ever dealt with healthcare system will tell you otherwise. From being denied necessary medical procedures because insurance doesn’t agree with it to subpar quality of care because how stretched the doctors and healthcare professionals are, US medical system is far from treating everyone well.
