No, I don't support privatisation, paying for appointments, an insurance system etc. I support continuing to pay for free at the point of delivery healthcare through taxes.
The US system is awful, very expensive and actually very inefficient. Many people end up paying more through insurance than they would for a tax funded system. Many employers keep workers on casualised and part time contracts rather than pay for "benefits" such as health insurance. My friend in her early 60s really struggles to get migraine medication as insurance companies change their policies for it.
And because insurance is risk based, surviving cancer, or living with it for a few years past initial diagnosis, can be really devastating. I had a friend (who apparently died a few years ago) who had a reasonable income in retirement and lived in Manhattan until she was diagnosed with cancer. Her treatment was quite successful but her insurance didn't pay all the bills, and then there's the issue of being insured as a survivor in her 60s or 70s.
Here, my dp is 60, overweight, smokes and has epilepsy and other long term conditions, diagnosed in his late teens, plus more recent issues over the last few years. I'm in my mid 50s and have never smoked, but also overweight and unfit with some problems and a recent diagnosis of type 2 diabetes. I have been very short of money for the last few years but things are now looking up a lot, but if one of us, or one of our kids, gets seriously ill, this will probably affect our finances again quite badly, but in a system like the one in the US, it would be just devastating. My mum was diagnosed with advanced cancer, and lived for 6 years 8 months afterwards, over 4 years from a terminal diagnosis, much longer than expected. I know of other people who live longer, whether or not they're ever in remission. An insurance based system can't possibly cover everyone against the possible complications and recurrences of cancer, dementia, old age and everything else.
