Changing the focus from politics to profit is not focusing on what is best for patients. It's moving from what is best for politicians to what is best for shareholders.
Although having poorer people die because they can't afford healthcare would do a great deal to reduce the total cost of healthcare. It's efficient. It's not nice, but it is efficient.
Its pretty simple, country keeps spending at same levels, country goes into massive recession, country can't borrow money anymore as no one will lend it, the "current" NHS, stops, flat out, we can't afford any of it at all.
Another option is privatise it, put in a healthy regulation system, make it easy to switch plans without being penalised financially, and put in better starting provisions for dealing with things like pre-existing conditions and esesntially make "HMO" style opterationg illegal.
Some healthcare will improve, some will get worse, the option for better treatment is always there for anyone, sure some won't be able to afford it, MORE would be able to afford it than can now. The country saves billions upon billions a year(largely just in people who actually wait a cold/flu out rather than waste everyones time with it, sprained ankles, basic crap that simply needs a bit of rest that people waste FREE services with), the country doesn't go into a massive recession, and we can afford to, you know, keep the country going.
A ridiculous number of people I know have had crappy treatment on the NHS, I've had years and years of absolutely awful treatment by the NHS, and it is getting worse constantly.
