Japan

I am a little confused on what exactly the medical re-investment fund entails. Do ALL the profits that doctors make go into the fund? or does a percentage of their total salary go into the fund? The goal of the fund is great--however, since Japan offers a universal health care system..it is important that all people using the system pay into this fund as well..not just doctors. The fact that a fund exists solely for the advancement of medicine probably contributes to the high life expectancy and high medical technology found in the country--and thus, enhances the overall health of Japan's citizens.
