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.
