Can't say this is an area I'm well versed in, but my two cents...

NHS scares me. From what I've heard there is no competition in this type of system, so you've got to put up with whatever they give you versus private where the competition is fierce and vying for your dollar. Reseach is much more prevalent in countries without NHS, and although they are having a tough time without thinking a drug cures everything, they do do way more research and make having access to health care much easier. Where there seems to be an issue is getting health available to all and frankly, I don't know how this can be solved because if the government gets involved then we'll be relegated to policies and red tape and people will complain about that and how service will either probably deteriorate and/or be denied. So for now, my endorsement is for private. Maybe we can have both? Private for those who want / can pay and public for those who can't get coverage due to type of job and/or disabilities.
