For so many years I was highly-supportive of a universal healthcare with a single party payer...
After 2 1/2 million dollars in care for myself... I have learned some incredibly difficult lessons:
1) having one's medical records, as well as all other records in a centralized place--is contributing to a take-over of personal privacy. I'll tell you: no "other" ever really knows a person--no matter how much medical information is accrued. In my case, it led to near devastation of my ability to survive (apparently I am no longer considered "hireable"--a terribly-limiting thing in this economy)... loss of identity that could have produced a "zombie" had I not been so well-educated, spiritually-astute, intelligent, and had so many physician friends who could intervene, and, as well, I have been effectively "dismissed" as a worthwhile person by many: in spite of my many, many contributions to society and my Church.
2) There is no way to expunge the faulty and damning medical records (even though the proof of the wrongfulness is available, and mostly public). It seems that by being a "Medicare" patient--there is no way to have the records investigated (by statute, the only thing that can be considered are the medical records themselves--not testimony by physicians, myself, outside research (no matter how "legit" it is), or even family members.
3) Medicare has no venue for not paying providers who give substandard or harmful care... so there is no help there, either. Each person is so complex (often) there simply cannot be enough "statutes and laws" in place to cover all exigencies... therefore, the use of a "single party payer" will end up in failure and damning the persons who need help: totally aside from the financial burden we cannot take on at this time.
4) Socialized medicine (you really need to look up leowolfvine's blog for some telling thoughts on this) is producing such dependent and helpless people--who, in their lack of respect for themselves, foist onto others their entire well-being... never learning from the lessons of life and sufferng. I'm not saying there aren't people who can't support themselves (particularly in this economic collapse)--but many have no chance at all in that kind of system. Only the few who are creative and well-educated (I'm not talking about degrees here)... enough to figure out how to survive on their own are "making it"... but right now, even those are having a hard enough time (particularly after being "labeled" as "sick": this has been stigmatized so badly--no one will give them a job--even if they are capable). After all, the records ARE available (in spite of HIPPA laws)--and people "talk"!
