This is similar to the Situation with affordable care act in the US. I think max vs min age premiums are capped. Which means old people get a deal, and young people overpay. If people paid their true cost to the system, insurance would cost $50 if you are 20, and $2,000 if you are 70. The same thing ultimately happens here where the young and healthy leave the public pool, leaving the older and sick. As rates go up, the cycle continues. I don’t see how anything except a $0 for everyone really works. Otherwise you just have people gaming the system (like the 50 year old in your example working a year of low paying job to qualify)
