Actually it was the mid-80sthey began. When I was in high school my father's company went HMO and we could no longer see our GREAT family doctor. We had to switch to some clinic where there was a revolving station of docs. No choice, you got who was available. I had to go twice... they were not nice, they didn't give a cr@p, they spent less than 10 minutes with you, but the wait was over 30.
