It Really Isn't Fair to Compare European Countries
Health care systems to that of the United States.
In most cases the former built their state systems when their wasn't a long established priviate system, and or out of socialist "ideals" post WWII (or in some cases WWI)
England/UK there wasn't anyone else to run hospitals and or "health care" system, so the government stepped in, created what there is now and that was that.
For all cases there isn't one European country that can match the population of the United States. Furthermore most all European governments run on the Parliamentary system. It is much easier for a platform to advance when the head of government needs to keep his party in power, and or broker deals with other parties to keep themselves on top.
Contrast that with the United States where power is divided between three branches, and the president has no direct power over Congress and the Senate, and vice versa. Oh the person sitting in the Oval Office does have lots of carrots and sticks to put about, and some power in his own right, but when push comes to shove those sitting elsewhere are more likely to look after their own political survival than go along with scheme that proves unpopular with their district.
Another problem for the United States is many people have health insurance they are quite happy with. No, these are not all "fat cats" and "Wall Street" types, but union members, government workers and such. If the government creates a plan that is overly generous,and costs less than a priviate plan, then people will naturally move over to the government health care system. If enough of that happens costs for those in priviate schemes will rise.
Other fly in the ointment is that for a government health care plan to truly work, and not break the bank, the federal goverment will have to do something it has not done very much of so far; contain costs by using it's buying power. In a country where the military spends several hundred dollars for ONE toilet seat that could be purchased at any supply house for ten dollars, you can see where this will lead.
The other way to keep costs down is to limit access to care and or treatments. If a 75yo man requires expensive treatment for a chronic condition that may only extend his life by a few years, is the cost worth it? Someone somewhere is going to have to write rules and make decisions. It just simply not possible to write a blank check on this issue.
One persons cost cutting, is another cutting another persons income. Now some may say that doctors are over paid and could use a "haircut", but that is not really true. Many areas of the United States have few doctors, especially general practioners. The federal government could offer to pay doctors willing to practice in "underserved" areas more, but that means money has to come from someplace else.
This is the reason so many people are leary of Obama's government health plans. Quite simply there aren't many easy choices to make. To remotely cover even half the current uninsured persons in the United States is going to cost quite allot of money, money the federal government does not have, and both the White House and Congress are loathe to raise taxes. You cannot pay for a scheme of this size with the usual gimmicks and budget slight of hands that normally goes on in Washington, DC. T
