I wouldn't claim to know all there is to know about the US system, and it's probably true that I live in a part of the UK which is served quite well by the NHS, although I accept it has its issues.
My knowledge comes with having two primary breast cancer diagnoses within two years and having had 8 lots of chemo plus radiotherapy for the most recent one. I have to say that I have had fantastic treatment on the NHS. It was prompt, professional and delivered with kindness and sensitivity by the staff.
I am on a few closed on-line groups where there are fellow breast cancer sufferers from all over the world. I am frequently shocked and saddened by women in the USA who are unable to complete treatment because they don't have sufficient insurance cover to pay for it or they have an insurmountable excess to pay. The cost when paying private is extortionate, because private healthcare, like all insurance based services, pushes costs up. Also, many of them have to continue to work throughout the treatment as employment laws seem to be abysmal at protecting them from dismissal during their illness. And if they lose their job, they lose their health insurance.
I also think that they may be overtreated at times. I read of many women, with small slow growing, less dangerous breast cancers in one breast, who have double mastectomies rather than a breast saving lumpectomy. I have a suspicion that what the customer wants, the customer gets, even though the customer has little understanding of risk and may be harmed by what is, in fact, a very brutal treatment. Of course, parent choice may be king - but I do have reservations.
That said, I'm quite upset by the approach of the NHS to surveillance after treatment. In parts of the UK, and I'm in one of them, there is no routine surveillance after formal treatment ends and you are deemed to have no evidence of disease - NED. I have an aggressive cancer and quite a high likelihood of recurrence and spread. I'd quite like to be scanned every six months/annually just in case it raises its head again. Here, they say catching it early won't help your chances of survival. I DON'T believe that and I haven't yet had an answer from a clinician to my question as to what they would recommend if it were their own wife, daughter, mother etc. In USA, they are regularly monitored. Maybe I don't have a proper handle on risk or maybe the NHS simply doesn't have the money to keep me safe. I'll be paying privately for scans.
