As we all know, any country has good reasons to want its citizens to be as healthy as possible. This led to the introduction of a health service in many countries. France has developed into a country in which all citizens can get most of the health treatment free. The money for this is partly from the people who are willing to offer.

But there are different opinions about the Health Service. The number of patients treated every year and the cost of treatment are much greater than expected. This means that the people who work for the Health Service --- doctors, nurses and other hospital workers, have much more work to do, and as a result they have little time for preventive treatment.

However, the tough problem is that as many people are able to receive treatment more expensive than they can pay, sometimes people go and visit their doctors when they don’t really need to. As there are many patients, doctors cannot spend time long enough with each patient. So some people prefer to pay for their own treatment so that their doctors can examine them more carefully. In fact, some rich people feel that they should pay more free money, which would be given to other citizens.
