Tying medical insurance to employment and insulating the patient from both insurance and direct medical costs has been a disaster.
Group insurance in general is an enormous scam. I personally think that the relatively constant costs for health insurance - both a result of group rates and employer-linked insurance - have led people to do far less for their own health (including over-reliance of doctors).
There are two things most people don’t seem to remember. One, the human body has a very effective immune system. Two, you can take care of yourself.
