I think the Scandinavian health systems are better when it comes to preventative care than the German system, because in the Scandinavian systems, the government is really more active in defining treatment, goals and defining health priorities. The German system is a competitive system with little government intervention. The price for this is that the government cannot set a health agenda. And the Scandinavian systems have little competition, so you often do have waiting lists. But on the other hand, you then have the government which can push for prevention.

The quality of health care in Germany is not as good as people sometimes believe it to be. We have problems with chronic diseases. The German system allows too many hospitals and specialists to treat chronic diseases. We do not have enough volume in many institutions to deliver good quality, and we do have fairly strict separations ... between primary physicians, office specialists and hospital specialists. But I think the quality problems can be solved in the next couple of years, and we have made major progress in diabetes, coronary artery disease and pulmonary disease care.

I think we have in Germany too many sickness funds. We started with more than 1,000 sickness funds. But the fewer sickness funds there are, the less bureaucracy and the easier the system is to operate. But it is important that the best sickness funds survive.

In the '50s and in the '60s, the private insurance system originally was a benefit for the bureaucrats in Germany. And this system became ever bigger because the private insurance industry lobbied successfully for making this system bigger. In the '70s and in the '80s, they managed to find a system where they could take everyone beyond 40,000 euros income per year but didn't have to take everyone. So they only took those that had both high income and a secure job and who was not ill at that time.

I think, unfortunately, many opinion leaders in Germany - including government officials, politicians, social service bureaucrats and so forth - they are in the private system, and they get paid the private insurance by their employer. So for them this is the best of two worlds: They have some more expensive and privileged access, but they do not have to pay for it themselves. This is a system which is both inefficient and unfair at the same time, but it is defended by those who profit from this system, and this includes many opinion leaders and many politicians.

In comparison to the U.S. health care system, the German system is clearly better, because the German health care system works for everyone who needs care, ... costs little money, and it's not a system about which you have to worry all the time. I think that for us the risk is that the private system undermines the solidarity principle. If that is fixed and we concentrate a little bit on better competition and more research, I think the German health care system is a nice third way between a for-profit system on the one hand and, let's say, a single-payer system on the other hand.
