A lot of American Doctors, that I have come accross on forums etc. tend to be of the opinion that you should pay for the service just like anything else. Medical insurance pays for the bills, which is fine while the population is working. However, at the moment, with high unemployment, people are unable to pay for medical insurance and a lot of doctors are losing their jobs. So the American system is quite good, right up until the economy goes wrong.
However, the UK can not afford it's current level of medical provision either. Because it has been payed for by tax money, the NHS is very good at promoting people because they have been there a long time, and not because the role needed to be in place. A consequence of this is that the NHS has a lot of middle ranking professionals who are paid quite a bit, but do not deliver a viable roce. Like the American system, in order for the NHS to continue, people need to work. No work, no tax revenue, no hospital.
The danger of giant, tax guzzling public services are a bit of a horror for Americans. They do not have the urge to change this, since they believe that you get what you pay for and if it is a free, state run hospital, the service is going to be inferior.
However, the ideology of health care asside, the Federal govt can not afford to fund that sort of opperation. If you want to know where all of the money for a viable health care provision is, it is cruising around the seas playing top gun politics with various surface fleets. It is in Afghanistan in considerable force and it is along various boarders lookiing for a decent enemy to fight.
A military the size of the US's does not come cheap. One of the comments made by a British soldier stuck with me. They have everything. Their troops have body armour, more food than you can shake a stick at, a selection of weopons, electronic gear etc. In short, everything that money can buy. That is where the US healthcare schemes are. It has been an American ideology for pretty much the entire 20th century that the US would be a world power. Funding that sort of dream takes sacrefices. Introducting a broard spectrum health system, complete with hospitals, university hospitals and local level clinics would actually take more money than the US has available to it. bear in mind that they have a lot more citizens that us and larger distances to do it on. You might make an urban health care system work, but having a medical provision for every citizen in the US would pretty much bankrupt them, even if they drastically reduced arms spending, it would take years and billions upon billions of dollars to implement. Getting to the Moon would seem easy in comparison.
